Really, if you think about it, both functional and procedural programming are exactly the same as programming in assembly language. Returning a value from a function pushes that value onto the function call stack, which is really just a disguised assembly MOV command. -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
