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

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
