Any code I post here should be considered experimental and unfinished. Don't use it in a production environment. It is your own responsibility to evaluate the code's fitness for any purpose. Programming isn't done in a vacuum, so be prepared to do your own research and teach yourself to do better.

Most importantly, all your polite critiques, elaborations, and corrections are heartily welcomed.
