Yes, the bitmap structures used to encode the structure of stack
frames. These *look* like they might be reusable for mix-and-match
arrays in Haskell-land. If so, that could be a pretty cheap new
feature.

It appears that the RTS has more flexibility in its array representations
than users can access through primops. In particular, there are
"pointers-first" and "bitmapped" arrays. Are these used for the evaluation
stack or something? I'd be very interested in getting user access to some
of this
