as of e941bd5cf64033c3fc8d072ec2bd7d4bffc6a959 on GHC 8.0, i get the following warnings

src/ParamRules.hs:5:1: warning: [-Wdeprecations]
    Module ‘Control.Monad.Error’ is deprecated:
      Use Control.Monad.Except instead

src/ParamRules.hs:6:1: warning: [-Wdeprecations]
    Module ‘Control.Monad.Instances’ is deprecated:
      This module now contains no instances and will be removed in the future

src/ParamRules.hs:32:17: warning: [-Wdeprecations]
    In the use of type constructor or class ‘ErrorT’
    (imported from Control.Monad.Error, but defined in transformers-0.5.2.0:Control.Monad.Trans.Error):
    Deprecated: "Use Control.Monad.Trans.Except instead"

src/ParamRules.hs:58:53: warning: [-Wname-shadowing]

src/ParamRules.hs:72:10: warning: [-Wdeprecations]
    In the use of type constructor or class ‘ErrorT’
    (imported from Control.Monad.Error, but defined in transformers-0.5.2.0:Control.Monad.Trans.Error):
    Deprecated: "Use Control.Monad.Trans.Except instead"

src/ParamRules.hs:73:27: warning: [-Wdeprecations]

    (imported from Control.Monad.Error, but defined in transformers-0.5.2.0:Control.Monad.Trans.Error):
    Deprecated: "Use Control.Monad.Trans.Except instead"

theses should probably be cleaned up or CPP'd over before a release with fixed up GLR support is done (cc @thomie )

Pretty sure this is fixed in my latest PR (already merged).
