Then DMD needs to be changed to handle incomplete source files. I'm no 
expert on this topic but wouldn't it be enough if the lexer and parser 
can handle incomplete source files? That might be feasible to complete 
during a summer.

I'm thinking it's very ambitious too.

Yes. There's no magic to use DMD as a library. Just compile all the 
necessary files and create a library out of the object files. It's been 
possible to do this for as long as DMD has existed. We just created a 
Dub package and some utility functions to package it nicely.
