Yes! I cannot stand sitting through conference talks on 'generics' that only
talk about 'collections'. This could be solved if we had typed arrays. If
anything we would get better talks on Generics. :-)
Arrays of a type is one of the last cases where I need docblocks to tell my
editor about the types.
In my opinion, even if we would have some implementation of generics, having
typed arrays with a simple syntax would be awesome.
A syntax suggestion:
$array = stdClass[];
class A {
public stdClass[] $array;
}
Adding an invalid array member should throw TypeError.
I know there are way more edge-case situations to think of (for example: if
class B extends A, $b is of type B[], but holds only A's, can $b be assigned as
value of public A[] $a ?)

I do not understand the reasoning behind that. Is it because we really want
generics, but when the 95% use-case is solved we fear that there would not be
enough momentum to get that? I'd love to have generics too, but a very simple
array syntax would in my opinion still add a lot of value, even if we already
had generics.
