I don't think they should be required. I think there should optional declarations along with a compiler flag that checks for them if the user asks for it, like Perl has. > then you presumably want that to cover class attributes as well as > local and global variables.

Maybe the function they think __slots__ is supposed to implement is a legitimate one, and having a correct way to do it is a good idea. > But unless you know the type of 'x', how do you know whether it > has attributes 'i' or 'j'? If the compiler knows (through declarations, type inference, or whatever) that x is a certain type of class instance, then it knows what attributes x has. -- http://mail.python.org/mailman/listinfo/python-list
