Good Haskell Style

I like using underscores in values, and CamelCase in types---I find
that the extra space makes the identifiers more readable.  Despite the
fact that I tend to write code that follows these conventions (except
for bullet 4), I find the rules to be extremely arbitrary and I do not
think that they should be given any special status.

PS: While we are discussing style, what should be the blessed amount
of indentation ;-)  I vote for 2 spaces.
