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

<P>According to 13.9.4 [<A href="https://wg21.link/temp.expl.spec#1">temp.expl.spec</A>] paragraph 1, only non-deleted
function templates may be explicitly specialized.  There doesn't appear to
be a compelling need for this restriction, however, and it could be useful
to forbid use of implicitly-instantiated specializations while still
allowing use of explicitly-specialized versions.</P>

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