First of all, congrats on getting your first RFC out; despite the issues
brought up so far, the idea itself is certainly interesting :)

I was curious about whether it would be possible to perform this type check
outside of the function context as well? For example:

if ($array instanceof Foo[]) { ... }

From what I could tell, this is not part of the RFC.

As an aside, for the fun of it, I thought of this arcane casting syntax:

$arr = (int[])$arr;
