Because at first glance, this is visually only a tiny fraction away from

   (if c then f else g)  it d them a elsa b

which would be parsed in a totally different way. (Personally, I think that
if/then/else is useless in Haskell and just a concession for readers from
other programming languages. Having a plain old "if" function would have
done the job in a more consistent way.) Of course syntax highlighting
improves readability here, but code should be easily digestible in black
and white, too. Visual clues matter...
