<P>[Voted into the WP at the September, 2008 meeting.]</P>

<P>In order for two <I>template-id</I>s to refer to the same function,
13.6 [<A href="https://wg21.link/temp.type#1">temp.type</A>] paragraph 1, bullet 1 requires that</P>

<UL><LI><P>their <I>template-name</I>s refer to the same
template</P></LI></UL>

<P>This makes it impossible for two <I>template-id</I>s referring
to operator function templates to be equivalent, because only
<I>simple-template-id</I>s have a <I>template-name</I>, and a
<I>template-id</I> referring to an operator function template is
not a <I>simple-template-id</I> (13.3 [<A href="https://wg21.link/temp.names#1">temp.names</A>] paragraph 1)
.</P>

<U><P>Suggested resolution:</P></U>

<P>Change 13.6 [<A href="https://wg21.link/temp.type#1">temp.type</A>] paragraph 1, bullet 1 to read,</P>

<UL><LI><P>their <I>template-name</I>s <INS>or
<I>operator-function-id</I>s</INS> refer to the same template</P></LI></UL>

<P><B>Proposed resolution (June, 2008):</B></P>

<P>Change 13.6 [<A href="https://wg21.link/temp.type#1">temp.type</A>] paragraph 1, first bullet, as
follows:</P>

<UL>
<LI><P>their <I>template-name</I>s <INS>or
<I>operator-function-id</I>s</INS> refer to the same template,
and</P></LI>

</UL>
