Haskell source blocks?

Haskell source blocks?

I'm guessing Haskell and org-mode Babel aren't really a great match? After
installing haskell-mode, I've tried

#+begin_src haskell
doubleMe x = x + x
#+end_src

which isn't working . . . because it isn't allowed in the ghci?

#+begin_src haskell
let doubleMe x = x + x
#+end_src

works. However,

#+begin_src haskell
let doubleSmallNumber4 x = if x > 0
                            then x
                             else x*2
#+end_src

complains of a parsing error on else. How does Haskell work in org mode?

I use IHaskell with ob-ipython. It does what you want from babel and even makes in-line figure generation relatively painless.
