Looks like you're asking for union types. There was an RFC about this
before but it didn't pass, I don't know why.
https://wiki.php.net/rfc/union_types
I would also like to see union types added, as I can't type hint most
of my code in absence of them.
Regarding the type coalescing problem noted in that RFC, my solution
to that would be to do noting. If a function accepts float or int, it
should just pass either through unchanged. Passing any other type
should be an error without an explicit cast IMO.
