To me it's not about renaming variables, but rather avoiding to clutter the parent scope with variables, e.g.: $closure = function () use ($this->getFooBar() as $foo) { $foo->stuff(); } versus the current: $foo = $this->getFooBar(); $closure = function () use ($foo) { $foo->stuff(); } They are almost equivalent, but the first with aliasing would not declare $foo in the outer scope. A bit cleaner IMO. Cheers -- Jordi Boggiano @seldaek - http://nelm.io/jordi -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
