The other interpretation would've been that you want to wrap a C++
function so it can be used that way from Python.

For now, you have to go to the Python 'C' API to do it.  I just
realized that Python doesn't have any unary operator*, so we could
make the 

   foobar(*args, **kwds);

syntax work in C++.  Not implemented yet, though ;-)
