Hi @goldmedal, I have a few thoughts/questions about this: * I'm wondering how the type signature for something like `Variadic` and `VariadicAny` can be represented? In `get_valid_types` it returns what is passed in. * The list of possible signatures for `Coercible` and `Any` could be quite large if we're looking to list all possible combinations * I'm not sure how to handle `UserDefined`, it's doc suggests calling `ScalarUDFImpl::coerce_types` but we don't have a suitable list of types to pass into it to figure out the possible combinations, unless I'm missing something -- This is an automated message from the Apache Git Service.
