I think this is great.

It reminds me of a construct that Hack introduced called "as expressions":

With throw expressions the Hack assignment,

`$a =3D $b as string;`

would be equivalent to the PHP assignment

`$a =3D is_string($b) ? $b : throw new TypeError('$b must be a string');`

If this passes, it would be great to see sugary equivalents get added to
the language too.
