Comment:

 Good news:

 Simon Hegel is working on this and has added markup for examples, looking
 like this:

 {{{
 -- | Documentation for 'f'
 --
 -- ghci> f 3
 -- 15
 --
 f :: Int -> Int
 f x = x * 5
 }}}
 He's got a DocTest program that is the Haskell-equivalent of python's
 doctest.

 We're currently working on extending the Haddock API so that DocTest can
 get what it wants from the .haddock files.
