Extended Description

Consider:

template<typename T> int junk1(T::junk);
template<typename T> int junk2(typename T::junk);

The first of these (in C++14 onwards) declares a template variable initialized by T::junk, the second declares a template function taking T::junk as a parameter. They are disturbingly similar.

So Richard Smith suggested I should file a bug report to get some kind of warning in place under -Wvexing-parse.
