A dictionary of methods! Thanks. Boy, do I feel silly now. So I have a
more general question: A dictionary of dictionaries is slower than a
dictionary of tuples, right? Because when Python accesses a
dictionary, it produces a hash from the key and finds that in its hash
table. Producing a hash from a tuple is much faster than producting
two hashes and doing two lookups. At least that's what I'm assuming.
