Hi. I have a question about a possible way of unification of Nat and Natural. I've almost done that, but only in case of using integer-gmp. If I use integer-simple there is a completely different definition of Natural.
How I construct now naturalTyCon (to make `naturalTy` to use it instead of `typeNatKind`) : ```naturalTyCon :: TyCon naturalTyCon = pcTyCon naturalTyConName Nothing [] [natSDataCon,natJDataCon] natSDataCon :: DataCon natSDataCon = pcDataCon natSDataConName [] [wordPrimTy] naturalTyCon etc... ``` Now I have to check`DynFlags` in a few places to reimplement `naturalTyCon` in case of using `integer-simple`. Is there a way to avoid hardcoding of `naturalTy`? My colleague said that it would be nice to get `naturalTy` from an environment by something like `lookupTyCon`, but there are many functions whose don't use any environment like functions from `typeNatTyCons` list in `GHC.Builtin.Types.Literals`. Now I am going to use `DynFlags` checking, but it looks like an ugly way... -- Best regards. Rinat Striungis
