Ouch. I really messed up with this one. I apologize for wasting bandwidth
when a *much* better idiom is already available. Please erase all that I
said before :-) I assumed (wrongly) that I could not put a constant value
on the list constructor - however, I forgot that constants are objects in
Python as any other value <wink>. Coming from a C/Pascal background this is
easily explained...
