A previous proposal:

http://hackage.haskell.org/trac/ghc/ticket/1773

split the Arrow class, making (>>>) and (<<<) functions in Control.Category. This breaks programs that use Control.Arrow.

To avoid some of the breakage, the proposal is that Control.Arrow should re-export (>>>) and (<<<), imported from Control.Category.

This patch has been applied (xmonad was broken due to the change, so I thought it best to act).

I thought we had a process for API changes. I'm not sure what the right thing is here. I usually prefer to avoid re-exports because they create problems with warnings.
