This PR consistently implements union type checking. Note that in the cases where there wasn't already a type check in place, the code would have still crashed later, but it is much harder for a programmer to know what went wrong, because it wasn't thrown early enough, where they actually made the made method called, and instead was thrown from deeper in the internals.
