While I agree with your sentimentality, this is not something worth 
fighting over until a solid use case comes up.

Because of dub its already separated out when loaded in an IDE.

My estimate based upon my last evaluation around 6-8 months ago was it 
would take around a week of concentrated effort to get the lexer into a 
good state for use as a library. The parser would be ridiculous compared 
to this (includes AST).

Semantic analysis while needing to be callable shouldn't need its 
internals exposed.

Point is, you will end up needing a dmd developer even if we were to 
separate out the lexer today and get it into a good state. If he wants 
to leave it for now we should. He has a lot of other things on his mind 
which are far more important.
