There is Typed Racket, which is not Haskell but still pretty cool.
There is Shen[0]that has Haskell's type system with Lisp syntax, but I don't think it's much used - I haven't tried it myself.

> Haskell's type system
Shen's type system is probably better described just as expressive.
http://shenlanguage.org/learn-shen/types/types_sequent_calcu... gives a sense of the flavor.
Thanks for the link. Out of interest, have you play with Shen yourself? Did you build something with it?

I've only messed around in the REPL. https://www.youtube.com/watch?v=lMcRBdSdO_U gives a fairly practical introduction.
(I hope that Template Haskell would make this possible.)
