I suggest adding this as an orphan instance (Like Show (a -> b)) in a seperate module (say, Numeric.Function).

https://hackage.haskell.org/package/NumInstances It would not save much, because in a reasonably big project you will somewhen import a package that transitively depends on the module. E.g. 'diagrams-canvas' depends on NumInstances.
