Bug 36 – Error message generated by odd enum forward-reference (?) alias bug is cryptic

This is an obscure one. This code compiles, as expected: enum E { One, Two, Three } class A { alias void delegate(E) EDG; static void fork(EDG dg) { dg(E.One); } } But move the alias declaration after the function: class A { static void fork(EDG dg) { dg(E.One); } alias void delegate(E) EDG; } And you get the cryptic error: dtest.d(18): cannot implicitly convert expression (0) of type E to E Maybe this has something to do with forward referencing?
