Agreed. Though the original poster probably wan't interested, it's also
the case that Haskell can use the annotations to get polymorphic recursion
and OCamlists have to butcher the code by either rewriting into a sometimes
less clear form or applying the sledge hammer of the unsafe cast operation.

I think it makes sense to have the annotations *apart* from their use in
signatures. Someone else mentions the "debugging by adding type annotations"
style, which I've used a bit myself (I'm shameless) and has a lot of nice
aspects.
