This hal always been possible. But it's not reassigning, it's shadowing - which is a totally different beast. Shadowing builtins is bad style, but lokal to your context. Which can get nasty of course, if you do the above on e.g. module level. But you can't alter the values for True/False globally with this. Diez -- http://mail.python.org/mailman/listinfo/python-list
