Do not blame haskell, blame emacs, if emacs is so stupid.
Fortunately there is a better emacs mode which understands layout and if:

Do not blame haskell, blame emacs. The layout rule is simple to
understand and I think it makes attractive code. It's not haskell's
fault that the emacs mode chooses a bad indent so often.
There is a better emacs mode which gets the indentation right more
often, I find ;)
