I ported part of the DMDFE to Java, and found it quite well-designed 
(with the exception of the frequent use of globals). The gotos make it 
more readable IMO (compare the original to the Java version where gotos 
are replaced with exceptions, replaced with duplicated code, emulated 
with a bunch of booleans, or refactored into separate functions taking 
7+ arguments).

However, the DMDFE's organization relies on being able to declare class 
member functions separately from where they're defined, which is 
impossible in D (hint, hint, nudge, nudge).
