Please bring your Boost.Python questions to the C++-sig:
should work if you want round-paren subscripts. That won't help you
if you need assignment, though.
x(a, b) = 1
isn't legal Python.
If you need assignment, you need square subscripts:
x[a,b] = 1
For that, write thin wrapper functions and expose them as __getitem__
and __setitem__. See the Python docs
(http://www.python.org/doc/ref/sequence-types.html) for more info.
