That can be said about every syntax construct - if you never seen it before, you'd have to learn. <=> is used in Perl, Ruby and Groovy - so it's not exactly unknown thing we've just invented, and if you've seen it once, you'd never forget what it means. It has the form that perfectly describes its function, so there's no real confusion here. > have any idea what it does (the closest thing <=> could be is the > equivalence operator from logic, and that's not the case here).

So instead of $a <=> $b, you'd get something like \PHP\compare_function($a, $b) or maybe even \PHP\Ordering\compare_function? I don't think most people would prefer the latter. Operators exist for a reason, and comparison is a frequent enough case to make operator - especially one that has a long tradition in other scripting languages - warranted. -- Stas Malyshev smalys...@gmail.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
