PUBLIC Hi, In the attached program, I am typechecking two Haskell modules with GHC 9.0.1: `Imported.hs` defines some infix operators, and `Importer.hs` uses them. After typechecking the first one, I put it in the moduleNameProvidersMap and the HPT. However, when I am typechecking the second one, the fixity declarations of the infix operators aren't picked up correctly. I know they aren't because I have defined operators that only typecheck if they are parsed right-associatively. In contrast, if I put both the definitions and the usage into the same file (`Standalone.hs`), typechecking succeeds (as I would expect it to). What am I doing wrong? Is filling the `mi_fixities` field of the `ModIface` not enough to let importers see the correct fixities? Thanks, Gergo This email and any attachments are confidential and may also be privileged.
