           Summary: Tupple parsing(?)
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major

These two code snippets should be equivalent:

(http://dpaste.dzfl.pl/092d6296)
-----------------------------
import std.typecons;

struct Point {
  int x, y, z;

  Tuple!(string, Point) foo() {
    return tuple("foo", this);
  }
}

void main() {}
-----------------------------
http://dpaste.dzfl.pl/44e95825
-----------------------------
import std.typecons;

alias Tuple!(string, Point) DirPoint;

struct Point {
  int x, y, z;

  DirPoint foo() {
    return tuple("foo", this);
  }
}

void main() {}
-----------------------------

Alas later one fails horribly with
