Ah, that's cool, pym makes my little script superfluous, which is
good.  

The automatic conversion could be great. But I wonder, if it could be
made to "do the right thing" with floats as well? The pycall.py script
I posted just converts everything in the args-list to strings.  This
has the nasty side effect, that floats or ints are converted as well.
For example the "maxsplit" count of string.split() then cannot be
used, because the 3 in "split X---Y---Z --- 3" would be converted to a
string and Python rightfully complains: 

Traceback (most recent call last):
  File "pycall.py", line 27, in _anything_1
    result = getattr(self.mod, func)(*args)
  File "/usr/lib/python2.3/string.py", line 121, in split
    return s.split(sep, maxsplit)
TypeError: an integer is required

As sometimes strings like "3" are needed as well I don't think there
is a really easy solution to automatic conversion, though.

Ciao
