TH doesn't pretty-print classes without fundeps correctly
A class with no functional dependencies is pretty-printed with a spurious | character, like in this example:
class Abstraction c_0 a_1 |
where abstractL :: forall m_2 . GHC.Base.Monad m_2 => c_0 ->
Control.Monad.State.StateT ([(Ident,
Term)])
m_2
a_1
