Tobu, I like this idea. Deducting from an example is really another way to wisdom.
What struck me as most diffuclt to understand: abs(-5.5) - 5.5 -> you are using "-" as symbol for "will give the result", which is really, really hard to parse. Take something else, please. Unicode has THAT many cool symbols. Or just -> or -=> or whatever. Thanks for sharing that work! Harald -- http://mail.python.org/mailman/listinfo/python-list
