Description:
------------
Hi,

Actually, you can can create a Closure with any of this:

$closure = function() { return $this->method(); }
$closure = fn() => $this->method();
$closure = \Closure::fromCallable([$this, 'method']);

I think it would be greate to have a simpler way to create a Closure. I
suggest to add a simpler variant:

$closure = $this->method::function;
$closure = Class::staticMethod::function;
$closure = trim::function;

It mimics the functionality from MyClass:class and $object::class, so
the syntax is user-friendly.
Additionally, it does not uses a new keywork, so I think it has no
backwards compatibility breaks (or so I hope).
