          Issue ID: 13692
           Summary: alias this and is-expression anomaly
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: DMD

-----------------------------------------------
struct T {
  int[] x;
  alias x this;
}

pragma(msg, is(T == int[]));   // false
pragma(msg, is(T == U[], U));  // true (!)
-----------------------------------------------

I would expect both to be false, as the IsExpression with == is supposed to test for type equivalence, not implicit conversions.
