In fact, languages like Python strengthen that: not only *can* all objects be values, but they inherently *are* values. Everything that can be put into a variable is a value, and that includes functions, strings, bound methods, dictionaries, modules, types (classes), the lot. Everything is an object and everything is a value. It takes some getting-your-head-around, but it is immensely powerful and convenient! ChrisA -- https://mail.python.org/mailman/listinfo/python-list
