Hi, In attempting to implement an extensible interface field for Core bindings based on my previous interfaces patch, I've run into problems with deserialising the special type reflection `$trModule` bindings generated by `GHC.Tc.Instance.Typeable.mkTypeableBinds`. These bindings are then stored in the `ModGuts.mg_binds` along with the real exported top-level bindings of the module.
Specifically, attempting to load the iface right-hand side expressions with `tcIfaceExpr` results in the error "Iface id out of scope" from `GHC.Iface.Env.tcIfaceLclId`. My understanding is that this may be because the binding is attempting to look itself up within the interface loading environment, without being bound yet - though it's unclear to me whether this is the correct behaviour for these special type reflection bindings, or if there's some special treatment that should be instead applied to load these. Any advice on how I should proceed would be greatly appreciated. Cheers, Josh
