It isn't true that Python always requires explicit conversion:

Python 1.5.2 (#7, Jun  4 1999, 14:52:53)  [GCC 2.7.2.3] on linux2
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> 2 * 0.5
1.0
>>> 1 + 2L
3L

So there is a precedent for promoting integers to floats and longs,
hence omniORBpy's support for it.

Cheers,

Duncan.
