A couple of times recently I've come across this problem: I have a large list to sort and I need to the the "key=function" argument to sort appropriately. But I actually have the key mapping in a big dictionary. Now I have to make an intermediary function:
def key_fn(key): return key_dict[key] If a dict were callable directly, this would be unnecessary. Often the small extra complexity and compute time is not important, but in sorting a large list, it could be a significant difference. Is there some reason a subscriptable thing like a dict should *not* be callable? -- George [nitpicking...] -- http://mail.python.org/mailman/listinfo/python-list
