1794.template keyword and alias templates

Section: 13.3 [temp.names]Status: C++17Submitter: Jonathan CavesDate: 2013-10-04

[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 class Template> struct Internal { template using Bind = Template; };

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

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

Proposed resolution (March, 2017):

This issue is resolved by the resolution ofissue 1710.
