Re: RFC: Functional Interfaces

<?php interface IFoo { public function method() : int; } $cb1 = function () implements IFoo : int { return 42; }; $cb2 = new class implements IFoo { function method() : int { return 42; } }; ?> Are $cb1 and $cb2 going to be the same (do the same)? Is this just a new syntax sugar, or a really new feature? According to implementation, I think, you shouldn't extend "zend_closure" with "interface". If this is a sugar, lets implement it as a sugar (without VM changes). But may be I didn't understand the idea at all :) Thanks.

Review of the implementation from those of you that do that would be good :) Cheers Joe
