No other languages understand D calling or mangling conventions, but D can 
make functions with C, Windows, and Pascal calling conventions.  If you just 
do something like:

extern(C) export void func(int x) { ... }

You can then, maybe, make a DLL or something out of it which can be called 
from virtually any other mainstream language, since most things understand 
the C calling convention.
