Re: Type hints in array destructuring expressions

Hi,

- It has been requested several times on this list to stop using the wording "type hint" and instead write "type declaration" ;)

I've updated the RFC to use the "type declaration" wording, thanks for the hint :)

- When I see this example in the RFC:

$years = [["now", 2020], ["future", 2021]];
foreach ($years as [string $description, int $year]) {

I immediately think of a similar:

$years = ["now" => 2020, "future" => 2021];
foreach ($years as string $description => int $year) {

or:

$foos = [new Foo("one"), new Foo("two")];
foreach ($foos as Foo $foo) {

As the RFC tackles array destructuring expressions and not foreach loops (which is just an option to use array destructuring there) I think this is out of scope for the RFC. I've added it to the future scope section though as I think it would align with the current proposal. Thanks for the input! Cheers, Enno
