          Issue ID: 24441
           Summary: templated member functions/nested function does not
                    mangle correctly to C++ on Posix systems
           Product: D
           Version: D2
          Hardware: All
                OS: Mac OS X
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: emmankoko519@gmail.com

extern(C++) struct A
{
    void foo(T)(T a);
}

void main()
{
    A a;
    assert(a.foo!int.mangleof == "_ZN1A3fooIiEEvT_");
}

This assertion fails as the function parameters are not mangled as template arguments.

D's mangling : ZN1A3fooIiEEvi
