Yes, in fact, its partly already there. f2py has a _cpointer feature that
allows one to pass C/Fortran function pointers directly to computational
routines taking callback arguments giving C/Fortran speed also for
callback arguments. In scipy this feature is available for
codes that are wrapped with f2py 2.45.241_1926 or up. Some codes in scipy
are still handwrapped but in future they will be replaced with f2py
generated wrappers.
