1728. Type of an explicit instantiation of a variable template

Section: 13.9.3  [temp.explicit]     Status: CD5     Submitter: Larisse Voufo     Date: 2013-08-05

[Voted into the WP at the July, 2017 meeting.]

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

  template<typename T> T var = T();
  template float var<float>;   // #1.
  template int* var<int>;      // #2.
  template auto var<char>;     // #3.

(See also issue 1704.)

Proposed resolution (May, 2017):

This issue is resolved by the resolution of issue 1704.
