calling D2 routines from C routines on linux

[Charles Hixson]

I notice I've skipped the main reason.
What I'd like to do is build libraries in D that I can call from 
multiple languages.  C, Python, C++, Ada, Fortran, Lisp, whatever.  Just 
about every language has a C interface.  So if I can call the library 
from C, then I can call it from anywhere.  (Possibly except D.  Not sure 
about that, but I think the runtime functions might clash.)
