We don't ever want to write ugly, error-prone code with the argument it'll run faster. Which often it doesn't, either. Instead and more importantly debug, devel, maintain and extend time, _our_ time, will grow exponentially with every poorly written module we add. > `while' is giving me more clarity. When you grow custom to other, better methods they are actually much clearer to you, and everyone else. -- underground experts united https://dataswamp.org/~incal
