If it's strict subset of D, then it could be done in a lint-esqu fashion 
by statical checking for anything not in the subset. I could see this as 
a patch to DMD that makes no modifications to the processing aside from 
adding extra errors. Any legal D- should be legal D and do exactly the 
same thing.
