Comment (by duncan):
I dislike the asymmetry. The ++ operator is not commutative but we don't
artificially make it visually asymmetric. Why not take Ross's proposal and
use <> as in Data.Sequence.
For the sake of the discussion, perhaps someone should also explain why we
cannot just generalise the type of ++. There's a separate argument that we
should not.
Also, what is the purpose of the flipped append? Why do we want to
dedicate a symbol for flipped append? I use monoid operations a lot and I
cannot think of a single use of flipped append.
