I'm aware of Stackless, of course, yet I prefer to stick to standard Python
if possible.  My need for "non-simple" generators is not at all serious
at this stage.  Since it has been in previous projects, it is likely to be
in future projects, and I merely wanted to foresee problems and solutions
in an informal way, while looking at Python generators.

Maybe one could find how to chain generators in the same way one nests
functions, with some idiomatic writing for moving back and forth along
the chain.  Most probably, I'll try a bit harder if I ever have a real,
immediate need. :-) Stackless is a always there, too!

Thanks for the help you provided already.
