<P>[Moved to DR at the October, 2012 meeting.]</P>



<P>In 12.2.2.2.3 [<A href="https://wg21.link/over.call.object#2">over.call.object</A>] paragraph 2, the non-explicit
conversion functions considered for producing surrogate call functions
are those of the form</P>

<UL>
<TT>operator</TT> <I>conversion-type-id</I> <TT>()</TT> <I>attribute-specifier-seq<SUB>opt</SUB> cv-qualifier</I> <TT>;</TT>
</UL>

<P>This (presumably inadvertently) excludes conversion functions
with a <I>ref-qualifier</I> and/or an <I>exception-specification</I>.</P>

<P><B>Proposed resolution (February, 2012):</B></P>

<P>Change 12.2.2.2.3 [<A href="https://wg21.link/over.call.object#2">over.call.object</A>] paragraph 2 as follows:</P>

<BLOCKQUOTE>

<P>In addition, for each non-explicit conversion function declared in
<TT>T</TT> of the form</P>

<UL>
<TT>operator</TT> <I>conversion-type-id</I> <TT>()</TT> <I><DEL>attribute-specifier-seq<SUB>opt</SUB></DEL> cv-qualifier</I>
<UL>
<INS><I>ref-qualifier<SUB>opt</SUB> exception-specification<SUB>opt</SUB> attribute-specifier-seq<SUB>opt</SUB></I></INS> <TT>;</TT>
</UL>

</UL>

<P>where <I>cv-qualifier</I> is the same...</P>
