How they are explicit cast if you're not explicitly casing anything?

That's exactly what I want to avoid - having several forms of casts with
different rules. One is good, two is kind of OK, three is too much.
Especially as you won't even know which rules something as simple as
foo($bar) would invoke.

It's not a new, separate feature. It can not be separate from what
already exists in the language. That's the whole point of it - not
concentrating on one use case but looking how it sits together with the
rest of the language.
