My plan is to create frontend that would be much better than 
existing, both in design and implementation. I decided to work on 
this full time for several months.

Front end will not produce the same data as DMD front end does, 
so most likely it will not be suitable to replace existing C++ 
implementation. But since no information will be lost I will 
consider creating a separate project which would build output 
compatible with existing (not identical, I don't think that would 
be feasible).
