Ticket #50 (closed enhancement: wontfix)
Enable overlapping instances
|Reported by:||choener||Owned by:|
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"
