I'm not sure what you're referring to here, the definition is:

data UArray i e = UArray !i !i !Int ByteArray#

The ByteArray# is an unlifted type (but its representation is a
pointer to a heap object).

The BA# constructor also includes a length field. My question is whether that gets unpacked into the Array constructor (as in Data.Text.Array, not UArray).
