            Bug ID: 35576
           Summary: Template variables could use a -Wvexing-parse
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: t.p.northover at gmail.com

    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.
