16.4.5.9 <a href="https://wg21.link/res.on.arguments">[res.on.arguments]</a> p.1. b.3: The second Note can benefit by adopting recent nomenclature.
</p>

<p><i>[
Resolution proposed by the ballot comment:
]</i></p>

<p>
Rephrase the Note in terms of xvalue.
</p>

<p><i>[
Pre-Batavia:
]</i></p>

<p>
Walter Brown provides wording.
</p>

<p><i>[Batavia: Immediate]</i></p>


<p><i>[
Adopted at 2010-11 Batavia
]</i></p>



<p id="res-1362"><b>Proposed resolution:</b></p>

<p>
Amend the note in 17.6.3.9 [res.on.arguments] p1 bullet 3.
</p>
<blockquote><p>
[ <i>Note</i>: If a program casts an lvalue to an <del>rvalue</del><ins>xvalue</ins> while 
passing that lvalue to a library function (e.g. by calling the function with the argument 
<code>move(x)</code>), the program is effectively asking that function to treat that lvalue as 
a temporary. The implementation is free to optimize away aliasing checks which might be 
needed if the argument was anlvalue. &mdash; <i>end note</i>]
</p></blockquote>
