A depressing remark, which comes close to saying there is no true Haskell.
? 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.
It's one reason I hang mostly with Hugs.
Interesting. Does that mean Hugs98? How on earth do you manage without at least some of the above?
GHC pretty well repudiates Haskell 2010.
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.
May Haskell 2020 receive more respect!
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. AntC
