Mutability is not a property of symbols but of values. So it doesn't make sense to declare an identifier to be immutable. And mutability is tied to the object's type, not to individual instances. What you want can only be obtained if Python would have an immutable variant for each type or would add an immutable attribute to each object. -- Piet van Oostrum <[EMAIL PROTECTED]> URL: http://www.cs.uu.nl/~piet [PGP 8DAE142BE17999C4] Private email: [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
