this is getting a bit out of scope for this list. I propose to move further
questions about general Cython usage to he cython-users mailing list.

As long as you take the decision at a per-module basis, sure. If you want
to mix them inside of a single module, then it's either Cython+C or Swig+C,
not all three. But as Antoine suggested, unless you really want an
identical mapper for whole range of different languages, Swig is likely not
what you should use these days.

Probably worth expanding your imagination. :)
