Oh, because it's not a proper data type! The data type is an expression,
and is held in a structured form, of which such powers may be one level.
This is better regarded as an optimisation of a common case than a true
data type. Now, there MAY be such a language that supports such things
as a proper data type, but I don't know of one.
