I see. Maybe there should be a separate function
efficientConstrEq :: Constr - Constr - Bool
so that people don't get confused with the standard Eq definition? How
often is the efficient version needed?
In any case, it seems like we should document the fact that the Constr
Eq instance doesn't
These don't seem to have Data instances in 6.4.1:
Language.Haskell.TH.Exp
Data.Tree.Tree
I guess there are probably a lot more, I just ran into these today. Is
there anything which prevents proper 'deriving' clauses from being
added to their definitions?

Simon PJ,
Is that Ok?
Should I?
