Paul, you're suffering from an extremely bad case of
tunnel thinking.

You wouldn't pass around 20,000 variables. You would
pass around a very few objects (in most cases probably
just one, i.e. a buffer) from which everything else you
need can be gotten to if and when you need it.

I'm not sure what you think "lexical" means, because
according to most people's definition, Python's scoping
is very much lexical, for both locals and globals.
