It would be pretty neat for Haskell hacking if the Emacs Haskell mode could do the following. Imagine you have written some code like so:

[...]

Binding a haskell-fold-source function to a key chain would enable you to get a quick overview of your module showing only the comments and type signatures. I've used the little function from http://emacs.wordpress.com/2007/01/16/quick-and-dirty-code-folding/ but it doesn't work well together with indented type signatures like in the example above.

AFAIU the problem, ..

data StupidTypeNameIntendedToBeLong = Foo

functionWithLoooongName :: Foo -> Bar functionWithLoooongName = undefined

.. you don't like the way haskell-mode indents the `-> Bar' line.

If this is the case, you could `newline-and-indent' (`C-j') right after `::'.

No, I like the way haskell-mode indents. :) However the simple folding snippet I linked to above doesn't work with it since that code simple collapses everything that's indented.
