closure, but no way to express it
So as my snobbery about programming languages has evolved, I've learned to love closure-based languages. As a result, something that's bugged me for a year or so has been something I read once-upon-a-time about Python not having true closures. How could it be that a language so pragmatically focused could omit something so imporant?
Turns out that it doesn't! Huzzah!
