It depends which ones. Some are implemented in multiple compilers in a
consistent way and widely liked and used, and are rather likely to make it
into the next standard version of Haskell in much their current form. (For
instance, portability is an important criterion for us, too, but we still
use multi-parameter typeclasses.) Others are still sufficiently
experimental that ideas really are just being played with. It would be
interesting to see a list of what people think will make it into Haskell 2
though.
