<P>[Voted into the WP at the November, 2010 meeting.]</P>

<P>According to Clause 13 [<A href="https://wg21.link/temp#2">temp</A>] paragraph 2,</P>

<BLOCKQUOTE>

In a function template declaration, the last component of the
<I>declarator-id</I> shall be a <I>template-name</I> or
<I>operator-function-id</I> (i.e., not a <I>template-id</I>).

</BLOCKQUOTE>

<P>This is too restrictive; it should also allow
<I>conversion-function-id</I>s and
<I>literal-operator-id</I>s.</P>

<P><B>Proposed resolution (September, 2010):</B></P>

<P>Change Clause 13 [<A href="https://wg21.link/temp#2">temp</A>] paragraph 2 as follows:</P>

<BLOCKQUOTE>

A <I>template-declaration</I> can appear only as a namespace scope or
class scope declaration.  In a function template declaration, the last
component of the <I>declarator-id</I> shall <INS>not</INS> be a
<INS><I>template-id</I></INS> <DEL><I>template-name</I> or
<I>operator-function-id</I> (i.e., not a
<I>template-id</I>)</DEL>. [<I>Note:</I> <DEL>in</DEL> <INS>That last
component may be an <I>identifier</I>, an <I>operator-function-id</I>,
a <I>conversion-function-id</I>, or a <I>literal-operator-id.</I>
In</INS> a class template declaration, if the class name is a
<I>simple-template-id</I>, the declaration declares a class template
partial specialization (13.7.6 [<A href="https://wg21.link/temp.spec.partial">temp.spec.partial</A>]). &#8212;<I>end
note</I>]
