<?php
interface IFoo {
    public function method() : int;
}
=20
$cb1 =3D function () implements IFoo : int {
    return 42;
};

$cb2 =3D 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" w=
ith "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. Dmitry.

Morning Internals,

    Please review the following RFC:

    https://wiki.php.net/rfc/functional-interfaces

    An implementation is provided, and is testable on 3v4l.

    Review of the implementation from those of you that do that would be
good :)

Cheers
Joe
