I've thought about refactoring the reflection parts of pyd into a 
reusable library for e.g. resurrecting RuD. Come to think of it, that 
would probably be necessary for supporting pypy.

It'd be a heck of a lot of work, though.



For your wrapper, you can probably do something like

extern(Windows) double vbwrap_test(double* inp,size_t num_inp,double* 
oup,size_t num_oup)
{
     return test(inp[0 .. num_inp], arg_oup[0 .. num_oup]);
}

with .dup sprinkled in as you see fit. And you don't need to explicitly 
copy the results back! Might need to take the ref off oup in test..
