On my side, I like the idea but the proposed syntax looks weird.
I would vastly prefer (and upvote) Levi's proposal:

[int $a] =3D [123]; // note: no brackets, this is a type declaration, not a
casting operation
[string $a] =3D [123]; // TypeError or implicit cast depending on
declare(strict_types=3D1/0) in the file
