Tastes vary, but I find that ugly. I much rather have the '=' aligned with 
the '|'.

data Foo a b
    = Foo      a
    | Bar        b
    | Foobar  a b
      deriving (Eq, Ord)

There, that looks good.

With the one exception that as a rule, in a multi-constructor type, none of 
the constructors should be identical to the type name (IMO).
