The generator expressions are amazingly powerful for the idea
of making producers and filters to be consumed. I love the guy's
example of log processing from multiple sources and custom queries
I haven't looked at Common LISP streams yet... The language is so big
that you can study it for ages and not scratch the surface :-)

I've been playing with Lua lately, and its co-routines make my brain
hurt :-) The end of the PyCon presentation gets into co-routines,
which I think might be in Python 3000. I haven't made up my mind
whether they're good or not.

I've only used them for @staticmethod in the past. I need to find some
good examples of what you can do with them before I know how they're
