LOL!

You just had to try that, didn't you?

Good ammo for obfuscated D. Nice to know inner classes have more than 
one use. ;)

:) I did small compiler for subset of Java once.
So I can predict typical problems more or less reliably.
That was just first what came up in my mind.

That inners... "Stay tuned" as they say and keep around
your favorite helmet.

Yes, since B is both a member of A and a subclass of A, it inherits itself.

A.B.B is the same thing as A.B, and so the compiler would reduce each 
long expression to the previous and so on.
