I like ::callable, personally, since it suggests the resulting type, but ::function would also be OK by me. > Another consistent notation is the cast: (callable) $obj->bar;. I think the analogy with ::class is stronger than the analogy with type casting (since it's not a variable or literal), although I'm not really too fussed either way. In terms of the feature itself (since I haven't weighed in yet), I think it's a reasonable piece of syntactic sugar, although I'd definitely want to see a patch before voting. :) Adam -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
