            Bug ID: 41309
           Summary: member functions shadow template arguments resulting
                    in "reference to non-static member function must be
                    called" error
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend

We reject

$ cat template-test.cpp 
struct S {
  template <bool foo> void f();
  void foo();
};

template <bool foo> void S::f() {
  bool b = foo;
}

void instantiate() {
  S s;
  s.f<true>();
}

with:

template-test.cpp:7:12: error: reference to non-static member function must be
called; did you mean to call it with no arguments?
  bool b = foo;
           ^~~
              ()
template-test.cpp:7:8: error: cannot initialize a variable of type 'bool' with
an rvalue of type 'void'
  bool b = foo;
       ^   ~~~
2 errors generated.

gcc/MSVC/icc all seem to accept it. I haven't checked the standard to see
whether we're getting this right and all the other compilers are getting it
wrong, but I'd be surprised if that were the case.
