+-- After simplification, the following fields change slightly:
+-- mg_rules Orphan rules only (local ones now attached to binds)
+-- mg_binds With rules attached
+--
+-- After CoreTidy, the following fields change slightly:
+-- mg_types Now contains Ids as well, replete with final IdInfo
+-- The Ids are only the ones that are visible from
+-- importing modules. Without -O that means only
+-- exported Ids, but with -O importing modules may
+-- see ids mentioned in unfoldings of exported Ids
+--
+-- mg_insts Same DFunIds as before, but with final IdInfo,
+-- and the unique might have changed; remember that
+-- CoreTidy links up the uniques of old and new versions
+--
+-- mg_rules All rules for exported things, substituted with final Ids
+--
+-- mg_binds Tidied
