but on export to HTML (or LaTex) I'd like to suppress the :{ and :} to just show the code

maximum'' :: (Ord a) => [a] -> a  
maximum'' = foldl1 (\x acc -> if x > acc then x else acc)

Also, this

#+begin_src haskell :results verbatim :exports both
maximum'' [1,3,5,2,4]
#+end_src

I'd like to export the code part with a > REPL prompt included, e.g.,

> maximum'' [1,3,5,2,4]

I once saw some similar tricks, but I've searched and searched and can't find them again. There's probably other html export formatting I'd like too, but if anyone can point me to that mystery doc I'd appreciate it.
