 Hi,

 GHC aims to change the behavior of overlapping instances to allow client
 code to overlap anything. If this does not make it into the next version
 of GHC to be released, could we have overlapped instances enabled in the
 library?

 I would like to specialize Show instances for RNA secondary structure, so
 that they read more like a biologist likes them, aka:

 "mkPrimary ACGUACU" instead of "fromList [A,C,G] :: Data.Vector.Unboxed"

 Gruss,
 Christian
