Python even has such a mechanism - but only for C functions. If you
ask PyArg_ParseTuple() to parse an argument as float or double, it
will also accept and convert integers.

There was some discussion on optional type specifications at the last
Python Conference; if something like that ever gets implemented,
we might succeed in getting such a type constraint mechanism as
a byproduct.
