I like your RFC.  I hope it is approved.  However, I would change your exam=
ples. Because, this one:

["now" =3D> (int) $now, "future" =3D> (int) $future] =3D ["now" =3D> "2020"=
, "name" =3D> "2021"];

You could do casting in this way:

["now" =3D> $now, "future" =3D> $future] =3D array_map('intval', ["now" =3D=
> "2020", "name" =3D> "2021"] );

If I were you I add examples with mixed types, like:

["address" =3D> (string) $address, "floor" =3D> (int) $floor] =3D ["address=
" =3D> "My adress", "floor" =3D> "3"];

I'm sorry my English

Regards
