While we're plugging logic programming languages, you might also be interested
in Mercury (http://www.cs.mu.oz.au/research/mercury/).  This is a
logic/functional language with Prolog-like syntax, but with a Haskell-like
type system, including Hindley-Milner types and type classes.
IMHO Mercury is even closer to Haskell than Goedel.

Also, see my recent attempts at (constraint) logic programming in Haskell:
