-- GHC has a source file to look at it when it needs to typecheck
-- a signature.  It's harmless to generate these modules, even when
-- there is a real @hsig@ file written by the user, since
-- include path ordering ensures that the real @hsig@ file
-- will always be picked up before the autogenerated one.
