so:
not quite (though I believe that would be close to Simon M's idea).
in my modification, both map and length would move completely
into the export section, length# would stay in the local section.
both sections would just be module <body>s., containing full
definitions, declarations, imports. to export anything, move it
to the export section, to hide anything, move it to the local
section (and in case that wasn't clear, these would be two
sections of the same module <body>, only distinguished by
whether or not their contents are exported).
cheers,

-- |iterate function over list
map :: (a->b) -> [a] -> [b]
-- |find length of list
length :: [a] -> Int
private:
map f (x:xs) = f x : map f xs
map f [] = []
length xs = length# xs 0#
length# (x:xs) n# = length# xs (n# +# 1)
length# [] n# = n#
and in order to see map's type or comment when i implement it, i
should see to other part of file. i personally prefer to have
public/private modifiers on each function and gather interface
documentation by tools like haddock
