 Amazing, I've wanted this for so long! Have you considered extending this
syntax to OOP, e.g. $obj->method(?) or SomeClass::staticMethod(?)?

One reason I'm personally excited about this proposal is that it would
allow static analysis in more cases, e.g.

$param =3D 'fooBar'; // What's this string? A user name? Elon Musk's favori=
te
color? Text of US Constitution?

somefunc($param);

function somefunc($cb) {
    $cb(123, 'meh'); // What parameter types does this accept?
}

Allowing syntax like $param =3D fooBar(?, ?); would indicate clearly what
this variable receives. Analysis tools would then be able to check if such
a function exists and whether it would receive parameters of expected types=
.
