Haskell 98 does an excellent job of being extremely simple, yet

how powerful it is. I suppose it just defies belief that you could
possibly need even *more* power than is already in the language...
and also, as I've mentioned, Haskell being simple is one of the most

Thing is, everything you can do in Haskell you can do in COBOL, as
they're both Turing-complete. That doesn't mean you *should*....
Features such as GADTs make it easier to express some things that are
harder to express (and harder to read once expressed) in Haskell98;
as such, they are a positive addition to the language.
Which doesn't mean every program has to use them --- I have yet to
write any code using GADTs. But I know they're there, and (roughly)
how to use them, if I ever do.
