<P>[Moved to DR at the May, 2015 meeting.]</P>

<P>It is not clear whether the <TT>template</TT> keyword should be
accepted in an example like</P>

<PRE>
  template&lt;typename&gt; struct s {};
  ::template s&lt;void&gt; q; //<SPAN CLASS="cmnt"> innocuous disambiguation?</SPAN>
</PRE>

<P>Although it is accepted by the grammar, the verbiage in
_N4567_.5.1.1 [<A href="https://wg21.link/expr.prim.general#10">expr.prim.general</A>] paragraph 10 does not mention the possibility,
while the preceding paragraph dealing with class qualification calls
it out explicitly.</P>

<P><B>Notes from the June, 2014 meeting:</B></P>

<P>CWG agreed that this usage should be accepted.</P>

<P><B>Proposed resolution (November, 2014):</B></P>

<P>Change _N4567_.5.1.1 [<A href="https://wg21.link/expr.prim.general#10">expr.prim.general</A>] paragraph 10 as follows (the
base wording is as modified by <A HREF="1887.html">issue 1887</A>):</P>

<BLOCKQUOTE>

The <I>nested-name-specifier</I> <TT>::</TT> names the
global namespace. A <I>nested-name-specifier</I> that names
a namespace (9.9 [<A href="https://wg21.link/basic.namespace">basic.namespace</A>]), <INS>optionally
followed by the keyword <TT>template</TT>
(13.3 [<A href="https://wg21.link/temp.names">temp.names</A>]), and then</INS> followed by the
name of a member of that namespace (or the name of a member
of a namespace made visible by a <I>using-directive</I>), is
a <I>qualified-id</I>...
