io,

While I am greatly enjoying your terse and good solutions (Even attempting to emulate your approach to answering questions to some extent), I find I do have a request. If possible, please use slightly more verbosity in your variables. It improves the readability of the code for us less fluent, and allows less expirienced monks like myself to focus on your construction more closely.
