That would be cool indeed. Seems to be a missing feature. BTW: I am normally
using boost::python (which IIRC has been used to wrap Qt4 one, too), which is
very comfortable (and may be used to wrap large libraries automatically using
pyplusplus, incl. partial recompilations), but most probably more "bloated"
However, on the C++-SIG list, Gustavo Carneiro announced his "pybindgen",
which is supposed to be very lightweight (but maybe not advanced enough to
wrap wx or Qt).

You can be sure that you are not the only one who would be very much
interested in such statistics.
