Yes, although I'm not quite sure what you mean.  Do you want to be
able to type

my_ext_func([3.0, 1.0, 4.0, 1.0, 5.0])

or 

my_ext_func(3.0, 1.0, 4.0, 1.0, 5.0)

?  If the latter you can't use PyArg_ParseTuple, but the `args'
parameter is just a tuple, amenable to PyTuple_Length & so on.

Cheers,
mwh
