Return doesn't really return

Yes, right. I forgot about that. The Clang API doesn't really have a way 
to represent the difference between "break" and "return" in D. The Clang 
API works like this:

* Return 0 - Stop visiting children
* Return 1 - Continue visiting children
* Return 2 - Recursively visit the children

It doesn't really seem to be a way to map the difference between the 
break and return codes that D uses to the Clang API.

Anyone got an idea for a workaround or should I just continue to use 
"break" and never use "return"?
