It should be, I did something similar and it worked. But it was
quite some time ago so I don't remember exact situation and any
details.
However you still be out of luck if the types you are trying to
use is present in header only, since there is simply nothing to
link with, so now you have to port whole template to D, or make
dummy wrapper in C++ that forces the compiler to emit those
symbols.
Same with ctor/dtors, if you have a class that is only used in
some executable and not present in any of a .lib/.a form you're
stuck. This is especially annoying with destructors because it
renders the whole thing unusable without helper libraries that
does new/delete in order to get the damn symbols emitted in
object files to be able to link.
