Summary

IsTuple returns Type | never instead of true | false but should another way round

Why

All type checkers (IsAny, IsNever, IsUnknown and IsTuple) expect to return true or false.

There are other types Exact and NonEmptyObject that need to return Type | never as they are used to validate whether 1. types are exact and 2. type is empty object. never provides a way to show TS error in these cases.

I'll put it on hold for now since there doesn't seem to be much demand
