There are two examples that you might want to look at:


The pickle3.cpp function world_getstate() shows how
you can process a python tuple or dictionary.
If you follow this route, your reverse() function
must expect a python tuple. Look at the
getting_started2.cpp example (very bottom) to see
how this can be done with an unbound helper function
without obscuring your C++ interface.

The do_it_yourself_convts.cpp example shows how you
can establish general mappings from Python types
to arbitrary C++ types. I am using this approach
to map Python tuples to boost arrays.
