Portability here is a tricky concept. Python is portable in the sense that
it rnus jsut about everywhere. However, there is another sense in which
it is much like interoperability. Python has a complete C backend, so in
theory you can easily interface with C code. However, Python objects
do not play well with C++ objects (which has given us a lot of grief in
the PyLith project). If everyone agrees that all OO is done by Python,
and any interface to C/C++ must go through the Python C bindings for
objects, than this might work. We should have done this in PyLith.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which
their experiments lead.
