<P>[Voted into WP at October, 2009 meeting.]</P>



<P>The list of entities that can be explicitly specialized in
13.9.4 [<A href="https://wg21.link/temp.expl.spec#1">temp.expl.spec</A>] paragraph 1 includes member templates of
class templates but not member templates of non-template classes.
This omission could lead to the conclusion that such member templates
cannot be explicitly specialized.  (Note, however, that paragraph 3
refers to &#8220;an explicit specialization for a member template of
[a] class or class template.&#8221;)</P>

<P><B>Proposed resolution (July, 2009):</B></P>

<P>Change 13.9.4 [<A href="https://wg21.link/temp.expl.spec#1">temp.expl.spec</A>] paragraph 1 as follows:</P>

<BLOCKQUOTE>

<P>An explicit specialization of any of the following:</P>

<UL>
<LI><P>...</P></LI>

<LI><P>member class template of a <INS>class or</INS> class
template</P></LI>

<LI><P>non-deleted member function template of a <INS>class or</INS>
class template</P></LI>

</UL>

<P>can be declared...</P>
