[Haskell-cafe] Haskell syntax/indentation for vim

[Dan Doel]

I hadn't seen this before, but I tried it out, and the parts I'm interested
in are nice. The indenting is less flaky than what I was using before
(comments had issues).

If you're rewriting things, though, it'd be nice to be able to customize
indentation a little more. For instance, I like laying out ifs like:

    if foo
      then bar
      else baz

But I like to lay out wheres as:

    foo = ...
     where
     bar = ...

But both the indents here are based on shiftwidth, so they're tied together.

Another 'nice to have' would be some intelligent outdenting. For instance,
if you type a let block right now:

    let foo = zig
        bar = zag
        in ...

That's what you'll get. It'd be nice if typing the 'in' snapped back to the
let. I know it's possible to implement something like this, because the
scala indentation mode I use frequently outdents when I type '=>' (which
annoys the hell out of me, because it's almost never correct), but I don't
know if it can be done intelligently enough to be useful (which would be
important). Something to keep in mind, though.
