Internals, As alluded to last week I have another RFC for improving the type system: [intersection types][1].
It allows parameters to define multiple type constraints that must be satisfied. Common combinations of our built-in types include `ArrayAccess & Traversable & Countable` and `Countable & Iterator`. Some people have suggest I merge this and union types into one RFC. For now I'll just proceed with them separately to gain feedback.
