    Summary:
    The fix for #12220 exposed some ill-typed programs which passed the typechecker
    in GHC 8.0.1 but now fail to typecheck in GHC 8.0.2. It's a bit difficult to
    characterize what exactly triggers this bug, but we at least have a minimal
    example and a simple fix to illustrate the problem and solution, so let's
    add that the the 8.0.2 release notes to advertise this change.
    
    Resolves #12784.
