Once remaining issues with shared libraries are resolved, it 
becomes feasible to use D code from dynamic languages. Clearly 
it's vital to provide easy path for calling it from Python, as 
it's used by most scientists. Although there's PyD, last few 
years saw rising interest in PyPy because it shows much better 
performance than CPython.
For PyPy, the way to go seems to be generating extern(C) wrappers 
for classes/functions/etc. + CFFI bindings 
(http://cffi.readthedocs.org/) for that C code.
First part of this can be reused for producing C++ wrapping code 
-- this is similar in goals to dtoh 
(http://d.puremagic.com/issues/show_bug.cgi?id=9285) but here 
entities to be wrapped should be explicitly mentioned. Extra 
benefit of producing C++ bindings is ability to call SWIG on them 
to support other languages. So, perhaps, C++ is the number one 
target in this respect.
