Hello all, MultiRec[1,2] is a great library for generic programming for families of possibly mutual recursive data types. Creating new generic functions might take some effort but the use of these functions is very straightforward. The multirec-binary[3] packages allows generic derivation of Data.Binary instances using the MultiRec library. Just try something like this:
import Data.Binary import Generics.MultiRec.Base import Generics.MultiRec.Binary
instance Binary MyType where put = gput MyFamily get = gget MyFamily
