<P>[Adopted at the February/March, 2017 meeting.]</P>

<P>The current wording of 13.3 [<A href="https://wg21.link/temp.names#5">temp.names</A>] paragraph 5 is:</P>

<BLOCKQUOTE>

A name prefixed by the keyword template shall be a <I>template-id</I> or
the name shall refer to a class template.

</BLOCKQUOTE>

<P>Presumably this should also allow <TT>template</TT> before alias
templates.  For example,</P>

<PRE>
  template&lt;template&lt;typename&gt; class Template&gt;
  struct Internal {
          template&lt;typename Arg&gt;
          using Bind = Template&lt;Arg&gt;;
  };

  template&lt;template&lt;typename&gt; class Template, typename Arg&gt;
  using Instantiate = Template&lt;Arg&gt;;

  template&lt;template&lt;typename&gt; class Template, typename Argument&gt;
  using Bind = Instantiate&lt;Internal&lt;Template&gt;::template Bind, Argument&gt;;
</PRE>

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

<P>This issue is resolved by the resolution of
<A HREF="1710.html">issue 1710</A>.</P>
