Hi, I don't know how to tag this kind of discussion (because it's not RFC request). I've interested in runkit PECL extension and think that it should be part of the PHP core runtime.
I do think that the implementation should be different and don't mind to suggest my implementation as RFC, but firstly I wish to know if you think that the core idea to be able to add extension methods to classes is good idea, so I won't start to implement a new feature without a reason (I'd start it but since I've saw runkit I think that we can discuss the idea first). I think that a code similier to this will be great: class Foo { public function foo() { } } class Bar extensionfor Foo { public function bar() { } } (new Foo())->bar(); // execute Bar method I see many pros about this feature, and you can see it in C# and ObjC too. Shall I open for it a wiki page and start RFC discussion? What do you think?
