Proposed resolution (March, 2017):

This issue is resolved by the resolution of issue 1710.

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

The current wording of 13.3 [temp.names] paragraph 5 is:

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

Presumably this should also allow template before alias templates. For example,

  template<template<typename> class Template>
  struct Internal {
          template<typename Arg>
          using Bind = Template<Arg>;
  };

  template<template<typename> class Template, typename Arg>
  using Instantiate = Template<Arg>;

  template<template<typename> class Template, typename Argument>
  using Bind = Instantiate<Internal<Template>::template Bind, Argument>;
