PS. a side effect of the for-in pattern is that I'm beginning to feel that Python might need a nice "switch" statement based on dictionary lookups, so I can replace multiple callbacks with a single loop body, without writing too many if/elif clauses.
PEP 275 anyone ? (http://www.python.org/peps/pep-0275.html)
My use case for switch is that of a parser switching on tokens.
mxTextTools applications would greatly benefit from being able to branch on tokens quickly. Currently, there's only callbacks, dict-to-method branching or long if-elif-elif-...-elif-else.
I think "match" from Ocaml would be a much nicer addition to Python than "switch" from C. -jj -- I have decided to switch to Gmail, but messages to my Yahoo account will still get through.
