Hi,
I wish for vim to honor my "autoindent on" setting and smartly indent
Bird-style literate haskell. E.g.:
... and now hitting enter at the end of the previous line should have
inserted ">       ", to place the cursor at the correct position for
typing "baz = c".

Sadly, I have no clue about vim syntax files and thus can't easily do
this myself, but it should at least be doable, since the C comments can
insert non-space indentation too.

cheers,
    Jan
