As someone who sees limited appeal in short closures (Ok, they may make for slightly simpler constructs that are slightly too complex for a regular “collect” type collection method), I see a *lot* of people spending a *lot* of time to save typing 8 characters (function). If this feature truly is about making it easier to read, then that should be your goal: make it easy to mentally parse, basically instantly. Given that even proponents of the approach are admitting the syntax can get quite hard to understand quickly, perhaps it’s time to accept that “more characters” !== “harder to read & understand” and importantly, “less characters” !== “easier to read & understand”. How long does it take someone to type function? A second, maybe two? How many times are other people going to read that, once it’s been written? Or maybe I’ve got it all wrong, and the goal is literally to save 8 keystrokes. If that’s the case, please update the RFC accordingly, to make it clear what the motivations are Cheers Stephen -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
