| The functionality of the `result` type function is special, with it being an exception as it'll create a type-pack union. Thus using the result type function will not require the developer to write an overloaded function type. |

Type pack unions do not exist in Luau. So, there's no way for a type pack function to produce a type pack union.

Yes, but result would be special cased. As its the only use for typepack unions.

There's not a way for us to do that right now. Type functions and type pack functions have to return types or type packs, and type packs are not unions. Doesn't mean we can't do this at all, but it does mean that this is essentially the same amount of work as proposing general support for type pack unions.
* Include `-` in all spellings of type-pack * Make reason for preferring not having type-pack union syntax more explicit.
