           Summary: Nested template member function error - "function
                    expected before ()"
           Product: D
           Version: 0.174
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: wbaxter@gmail.com


A template member function with nesting confuses the compiler.  It is fine with the equivalent construct existing outside a class.  It only breaks when you put it inside the class.

class Foo {
    template myCast(T) {
        T myCast(U)(U val) {
            return cast(T) val;
        }
    }
}

void main() {
  Foo foo = new Foo;
  int i = foo.myCast!(int)(1.0);
}

-->
Error: function expected before (), not 'foo dotexp template myCast(U)'

You can also easily trigger this IFTI problem with named template mixins:

template A()
{
  static void foo(T)(T t) {}
}

struct Bar
{
  mixin A!() a;
}

void main()
{
  A!().foo(1);  // works
  Bar.a.foo!(int)(1); // works
  Bar.a.foo(1); // error
}

Error: function expected before (), not 'Bar  dotexp template foo(T)'

This issue is a show stopper for the Arc v.2 release, unless we find a workaround of some sort.

Here is a patch to DMD 0.175 that fixes this issue (posted december 1st to the announce newsgroup). It is not really well tested, but illustrates that the required change is quite small.
