I have a custom class "Document" extending your "Document" to provide some additional high level functionality I need. I use the same approach like you with mixing in some XPath logic using a second class, which itself overrides some methods of your XPath class. This overriding does only work if I use C3 method resolution order, which I can't because of the error I get. Compilation only works if I either don't use C3, which results in my own XPath::XYZ methods not beeing called, or change your Styles class to not extend Exporter.
