No, it wouldn't. Any object that provides __hash__() and __eq__() can be used as a key. Nothing prevents using mutable objects as keys in Python. Egon Spengler: There's something very important I forgot to tell you. Peter Venkman: What? Spengler: Don't use mutable keys. Venkman: Why? Spengler: It would be bad. Venkman: I'm fuzzy on the whole good/bad thing. What do you mean, "bad"? Spengler: Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light. Ray Stantz: Total protonic reversal! Venkman: Right. That's bad. Okay. All right. Important safety tip. Thanks, Egon. Marko -- https://mail.python.org/mailman/listinfo/python-list
