It doesn't, systematically.

Most programs in most programming languages don't, in fact, do that.
They often have bugs from not trying hard enough to manage state, though.

Sure, seveal, but they are the techniques you learn in any introductory class in any structured programming language, though there's a good chance they were developed in a Lisp-family language.
