I made the minimal changes to make this work. But it looks like {:and, constraints} gets treated the same as just constraints, so I wonder if we can just get rid of {:and, ...} everywhere.

The Elixir docs say that a typespec of [] means an empty list.

I wasn't sure if the constraint should be applied to the input type, the output type, or both.

Fixes errors with certain schemas. I don't remember exactly what the schemas were that caused the errors. One of them was a union where one of the types was a custom type that was a cast or a union itself.
