<P>[Accepted at the November, 2020 meeting as paper P2096R2.]</P>



<P>It appears that partial specializations of variable templates are
intended to be supported, as 13.4.4 [<A href="https://wg21.link/temp.arg.template#2">temp.arg.template</A>] paragraph 2
says,</P>

<BLOCKQUOTE>

Any partial specializations (13.7.6 [<A href="https://wg21.link/temp.spec.partial">temp.spec.partial</A>]) associated with
the primary class template or primary variable template are considered when
a specialization based on the template <I>template-parameter</I> is
instantiated.

</BLOCKQUOTE>

<P>However, there is no explicit specification for how they are to be
handled, and the wording in 13.7.6 [<A href="https://wg21.link/temp.spec.partial">temp.spec.partial</A>] and its
subsections explicitly applies only to partial specializations of
class templates.</P>

<P><B>Additional note, July, 2017:</B></P>

<P>The term &#8220;primary template&#8221; appears not to be defined
in the current wording; the resolution of this issue might be a good
opportunity to add such a definition.</P>
