Hi,

the problem with foo(string $bar) and foo(string! $bar) or
foo((string) $bar) is that the writer of the method is deciding, not
the caller - but in both cases, the method gets exactly what it needs
to have, so the way how it should be passed should be upon the caller.

Also, this discussion shows why exactly is it a bad idea to have two
ways of passing parameters - it's a mess and there isn't an ideal way
how to solve it.
