+ *** NEW TASK??? ***
+ Implement "signature" objects.  These are alluded to in PEP 252 but
+ not yet specified.  Supposedly they provide an easily usable API to
+ find out about function/method arguments.  Building these for Python
+ functions is simple.  Building these for built-in functions will
+ require a change to the PyMethodDef structure, so that a type can
+ provide signature information for its C methods.  (This would also
+ help in supporting keyword arguments for C methods with less work than
+ PyArg_ParseTupleAndKeywords() currently requires.)  But should we do
+ this?  It's additional work and not required for any of the other
+ parts.
