While Haskell doesn't have full dependent types, as found in say Agda,
it (or rather GHC) does have some extensions that allow you to get
many of the advantages of full dependent types.

You may want to check out the documentation of: multi parameter type
classes, functional dependencies, type families, higher ranked types,
generalized algebraic datatypes, scoped type variables, pfff... we
have so many toys! :-)

You may also want to read some of the papers mentioned in:
