Re: [RFC] !instanceof operator - reaction measuremen

> The "instanceof" is counterintuitive for me compared to operators. Hmm interesting, might be possible to go that direction by making T_IS_EQUAL accept class_name_reference. I like that, biggest concern with this is what is the difference (if any) between ```php $object !== MyClass $object != MyClass ``` > If this isn't possible and !instanceof would be adopted, > what about the following in addition to the proposed example? I definitely agree that those make sense, but I would say that they should prob. have their own discussion, but would be much easier to get through if this one would be accepted. > Why not "not" instead? The "!" in front of "i" in > "!implements" Might be my limited knowledge on the subject, but by using not, we are making not a reserved keyword, which I think should be done really carefully.
