<P>[Voted into the WP at the July, 2017 meeting.]</P>



<P>It is not clear to what extent the type in an explicit instantiation
must match that of a variable template.  For example:</P>

<PRE>
  template&lt;typename T&gt; T var = T();
  template float var&lt;float&gt;;   //<SPAN CLASS="cmnt"> #1.</SPAN>
  template int* var&lt;int&gt;;      //<SPAN CLASS="cmnt"> #2.</SPAN>
  template auto var&lt;char&gt;;     //<SPAN CLASS="cmnt"> #3.</SPAN>
</PRE>

<P>(See also <A HREF="1704.html">issue 1704</A>.)</P>

<P><B>Proposed resolution (May, 2017):</B></P>

<P>This issue is resolved by the resolution of
<A HREF="1704.html">issue 1704</A>.</P>
