Last year I boiled down existing ddmd to:

https://github.com/zachthemystic/ddmd-clean/

I did it because I needed to teach myself programming, and maybe 
there was a long shot that someone would want to use it. I rather 
angrily attached the GPL license because I thought I had to. But 
flexibility in this area comes as a welcome surprise.

I want to make another point. Dmd is perhaps written in a way 
that might be easier to create an automatic program translating 
it to D than other C++ programs. I guess that approach is worth 
at least a small amount of investigation. The question is whether 
the number of special cases required to automate will take more 
toll than the grunt work of direct translation.

ddmd currently does some really awkward C++ contortions of stuff 
which is built into D. No one would write it that way in D. While 
I stripped down the compiler to make my lexer/parser version of 
it, which is very mangled at the moment, at least you can look at 
the code to see how dmd would look in D.
