It's a philosophical question whether it's smaller in a packed str

Consider a type that is a subrange of an integral base type, with an
explicitly specified bit size smaller than the bit width of a storage
unit.
When used for a standalone variable, its byte size is the same as that
of the base type, i.e., the type is padded to a whole unit.
However, when used
