 *                   Style sheet for the W3C specifications                   *
 *
 * Special classes handled by this style sheet include:
 *
 * Indices
 *   - .toc for the Table of Contents (<ol class="toc">)
 *     + <span class="secno"> for the section numbers
 *   - #toc for the Table of Contents (<nav id="toc">)
 *   - ul.index for Indices (<a href="#ref">term</a><span>, in § N.M</span>)
 *   - table.index for Index Tables (e.g. for properties or elements)
 *
 * Structural Markup
 *   - table.data for general data tables
 *     -> use 'scope' attribute, <colgroup>, <thead>, and <tbody> for best results !
 *     -> use <table class='complex data'> for extra-complex tables
 *     -> use <td class='long'> for paragraph-length cell content
 *     -> use <td class='pre'> when manual line breaks/indentation would help readability
 *   - dl.switch for switch statements
 *   - ol.algorithm for algorithms (helps to visualize nesting)
 *   - .figure and .caption (HTML4) and figure and figcaption (HTML5)
 *     -> .sidefigure for right-floated figures
 *   - ins/del
 *     -> ins/del.c### for candidate and proposed changes (amendments)
 *
 * Code
 *   - pre and code
 *
 * Special Sections
 *   - .note       for informative notes             (div, p, span, aside, details)
 *   - .example    for informative examples          (div, p, pre, span)
 *   - .issue      for issues                        (div, p, span)
 *   - .advisement for loud normative statements     (div, p, strong)
 *   - .annoying-warning for spec obsoletion notices (div, aside, details)
 *   - .correction for "candidate corrections"       (div, aside, details, section)
 *   - .addition   for "candidate additions"         (div, aside, details, section)
 *   - .correction.proposed for "proposed corrections" (div, aside, details, section)
 *   - .addition.proposed   for "proposed additions"   (div, aside, details, section)
 *
 * Definition Boxes
 *   - pre.def   for WebIDL definitions
 *   - table.def for tables that define other entities (e.g. CSS properties)
 *   - dl.def    for definition lists that define other entitles (e.g. HTML elements)
 *
 * Numbering
 *   - .secno for section numbers in .toc and headings (<span class='secno'>3.2</span>)
 *   - .marker for source-inserted example/figure/issue numbers (<span class='marker'>Issue 4</span>)
 *   - ::before styled for CSS-generated issue/example/figure numbers:
 *     -> Documents wishing to use this only need to add
 *        figcaption::before,
 *        .caption::before { content: "Figure "  counter(figure) " ";  }
 *        .example::before { content: "Example " counter(example) " "; }
 *        .issue::before   { content: "Issue "   counter(issue) " ";   }
 *
 * Header Stuff (ignore, just don't conflict with these classes)
 *   - .head for the header
 *   - .copyright for the copyright
 *
 * Outdated warning for old specs
 *
 * Miscellaneous
 *   - .overlarge for things that should be as wide as possible, even if
 *     that overflows the body text area. This can be used on an item or
 *     on its container, depending on the effect desired.
 *     Note that this styling basically doesn't help at all when printing,
 *     since A4 paper isn't much wider than the max-width here.
 *     It's better to design things to fit into a narrower measure if possible.
 *
 *   - js-added ToC jump links (see fixup.js)

   <p>In 2022-10, the C++ Library Evolution group conducted a series of
  electronic decision polls <span>[P2648R0]</span>.
This paper provides the results of those polls and summarizes the results.</p>
   <p>In total, 24 people participated in the polls.
Some participants opted to not vote on some polls.
Thank you to everyone who participated, and to the proposal authors for all
  their hard work!</p>

    <ol>
     <li data-md>
      <p>LFTS is not Fit-For-Purpose.</p>
     <li data-md>
      <p>It is unclear why we are polling this, given that (a) it utterly failed to reach consensus in LEWG (3-5-3-4-2) &amp; (b) is likely to be straw polled in Kona plenary regardless of the outcome of this electronic poll.</p>
    </ol>
    <p>My objection is that the intent of having that LFTS was to answer open questions before deciding whether or not to put these libraries into the IS.  With the exception of scope_guard, every library in the LFTS has had at least five years to get feedback; some have had seven years.  AFAIK, the purpose of the LFTS has not changed, so why are we not deciding what to do with the libraries in it?</p>
    <p>If the purpose has changed and now WG21 wants to keep these libraries in the LFTS forever, then we should state that clearly and unambiguously and ultimately vote on that, and stop pretending that the LFTS has a different purpose.</p>
    <p>Based on this history, I don’t believe that LFTS3 will get us any feedback on the one new feature proposed for it (scope_guard) either.</p>
    <p>The LFTS3 is itself misleading.  [general.plans] states:</p>
    <p>"The C++ committee intends to release new versions of this technical specification periodically, containing the library extensions we hope to add to a near-future version of the C++ Standard. Future versions will define their contents in std::experimental::fundamentals_v4, std::experimental::fundamentals_v5, etc., with the most recent implemented version inlined into std::experimental."</p>
    <p>While some committee members are okay with publishing knowingly misleading statements in non-normative sections of documents, I am not and will vote strongly against approving such a document.</p>
    <p>Another misleading statement from [general.plans]:</p>
    <p>"When an extension defined in this or a future version of this technical specification represents enough existing practice, it will be moved into the next version of the C++ Standard by removing the experimental::fundamentals_vN segment of its namespace and by removing the experimental/ prefix from its header’s path."</p>
    <p>If that isn’t our plan, I cannot sign off on it.</p>

    <p>Given that we have had 5-7 years to get feedback on all of the libraries in this document except for scope_guard, the time has come to eliminate it and decide once and for all if the features in this document should be added to the IS or not.</p>
    <p>As for scope_guard, given the lack of feedback we’ve gotten on the other features over the last 5-7 years, a LFTS3 with only scope_guard does not seem to be a good use of our resources.  LEWG should come up with a better plan to make the hard design decisions necessary to add scope_guard to the IS.</p>

    <p>The desire expressed by some for terser lambdas is not something we should try to paper over in the library.
This fails in the presence of overload sets and the name chosen aren’t great either.
I wonder how often this would end up being used, writing a lambda is probably faster, if only because that’s the intuitive approach powered by muscle memory.
If anything the examples suffer more of the clunkyness of std::forward.  Given https://wg21.link/p0644r1:</p>

    <p>In contrast to function_ref, I do not see this constructor as necessary, as bind_front with empty functor could be apple to achieve the same effects, i.e. it would be sufficient to make nttp callable.
