? There wasn't a true Haskell in 1998. Already Hugs (in HugsMode) and
GHC (with glasgow-extns) had MPTCs, FlexibleInstances/Contexts,
FunDeps, UndecidableInstances. Overlapping instances was optional
extra.

Interesting. Does that mean Hugs98? How on earth do you manage without
at least some of the above?

So does Hugs (in HugsMode): a large proportion of the extra features
in H2010 were suggested by the Hugs teams; and Hugs 2006 was already
far advanced beyond it.

I think you'll need to adjust your expectations: I doubt H2020 will
happen. There was a glimmer of activity last month, but this list has
resumed its moribund state. So I think we can put last month down to
dead cat bounce. If H2020 does happen, HugsMode will still be well
ahead of whatever gets added.
