--- The NoMonomorphismRestriction deals with a Happy infelicity
---    With OutsideIn's more conservativ monomorphism restriction
---    we aren't generalising
---        notHappyAtAll = error "urk"
---    which is terrible.  Switching off the restriction allows
---    the generalisation.  Better would be to make Happy generate
---    an appropriate signature.

 -- The above warning supression flag is a temporary kludge.
