Paul I wasn't referring to static languages and languages that are compiled to machine code such as C, C++, etc. Python is a dynamic object oriented language ... (almost verbatim from the website). It is compiled to bytecode and run on a virtual machine. I don't really think it would be possible or desirable to have strict access control (encapsulation) in the core of python. a) it would piss us all off. b) it would greatly impact on the dynamic nature of python. cheers James -- http://mail.python.org/mailman/listinfo/python-list
