I want to use ghc-6.9 for improved support of type families, but I see
that the change to the Arrow interface breaks some of my libraries
(since (>>>) is no longer a method of Arrow).  Will this
change really be in ghc-6.9?  Does anyone have coping strategies for
keeping libraries working in 6.8 *and* 6.9, particularly ones that
define instances of Arrow?<br>
