Re:Programming R at native speed using Haskell by chriswarbo on Wednesday September 09, 2015 @11:26AM (#10192004)
Sorry, I've not used Typed Racket so I can't comment. I've only played around a little with Racket itself, although I've used various Schemes in anger (and more Emacs Lisp than I'd like!)

One cultural issue, rather than a technical one, is that the whole of Haskell is strongly typed, lazy and pure; there's no getting away from it, so every idiom, library and API must take them into account. I imagine Typed Racket's ability to mix and match features will result in more "conservative" code (ie. choosing the type system to match a known approach, rather than inventing a new approach to fit the type system).

That's a good answer. I'm still fairly novice in Racket, so I don't yet have a good intuition for where Racket is asserting its own cultural norms. Haskell definitely communicates its concepts of purity early on, and so I can see where the community would continue to push itself in these directions.
