What are the plans for http://hackage.haskell.org/trac/ghc/ticket/5623 which
seems to be still open?
Quoting form the ticket ...
Just to spam a little more, it seems that the HEAD happily duplicates all
computations on unboxed types. It even duplicates x+x in this example:
foo :: Float -> Float
foo x = let y = x+x in y+yI haven't tested but this looks bad for
performance critical code.
