Since the struct module is designed specifically for C-style structs,
it's definitely not going to handle arbitrary-length integers on its
own.  You could chop up your Python (long) integer into C-sized pieces
and then pack the pieces; but if you need to do that, the advantage of
using struct at all may be minimal or even completely gone.

If you are sure you are going to keep using the same version of
Python, then this could work.  I would personally not depend on this
to keep working in future versions.

I'm not aware of any existing package that does what you want.  Maybe
someone else does.  How I personally would tackle your problem is to
write the whole thing from scratch (as you've done).
