So maybe we should just conclude that pretty printing should be left associative, building from the left.
To clarify, Duncan and I are now thinking that as pretty builds left-to-right strings, perhaps it is natural that the operators in a <+> b <> c <+> d <> e <+> ... should be left-infix, as it is natural to read this as "a then b, then c, ...". [Hmm, I don't know if that was actually any clearer, but a second phrasing can't hurt]
Should we reconsider Data.Monoid.<> if we can't make it work with the pretty package?
And if we do decide that pretty should have an infixl operator and Monoid an infixr operator, then I think there will be fewer headaches if they don't both use the same name. Thanks Ian
