Oh yes that’s right. I guess I would need some real examples of a function that used type information and could suffer a failure by the compiler assuming the wrong type from a constant like “1”. If you were deserializing you would probably be passing in a very particular type and not some ambiguous thing like a number literal.
Having said that there should be type restrictions for Integer, Real, Boolean and String (maybe Char) etc… Right now only class, record and interface are supported.
