Comment (by Edward Z. Yang <ezyang@…>):

 In [changeset:"0bef02e49fb2907989127d77ae61ed48ba87ae18/ghc"]:

 Apply GenMap to CoreMap and CoercionMap.

 Summary:
 The biggest chore is the Eq (DeBrujin a) instances (all the more a chore
 because we already have an implementation of them, but a CmEnv is not an
 RnEnv2), but otherwise a fairly mechanical transformation.
