something like the attached vim script might work for small sources
(ignores all layout rules and keywords, just records increase/decrease
of indentation stack; builds up a rather large pattern of positions for
highlighting via :match).
(don't assume that this is the only, let alone the right way to do this,
and please pardon my rusty vimscript;-)
bonus tasks are left as exercises for the reader..

ps. a good interface for teaching vim about language syntax and
motion would be nice (or at least a dynamically loadable,
position-independent GHC API for use with vim's libcall..),
but I find that with visual highlighting of lines and blocks, Haskell
layout manipulation at least tends to be fairly straightforward
(I do not even use highlightling of the cursor column, which gives
you a vertical ruler)

I'd like some more help from the editors in getting 2d layout right without trying. Here's a mockup of vim with vertical grey bars delimiting layout:

Does anyone know how to get this effect in vim (or emacs)?
Bonus points if the grey bars are draggable, changing the indenting. More bonus points for box-based navigation.
