newtype T = MkT Int#
Provided T :: # (i.e. unlifted), I don’t think this would be too hard. That is, you can give a new name (via newtype) to an unlifted type like Int#, Float#, Double# etc.
Worth a wiki page and a ticket.
There is already a ticket at least, https://ghc.haskell.org/trac/ghc/ticket/1311. Regards, Reid Barton
