> The alternative is for `[[t1, t2]]` to represent one valid set of types for a function of two arguments, instead of `[[t1], [t2]]`. This way we can constraint arguments together. We would need to check that each entry on the list has the same number of entries = arguments. This seems reasonable to me. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
