Sorry about that - I'm trying to cleanly separate the API from the internals; always_overrides is internal, and should be imported from peak.rules.core, not from the parent package. I can stick always_overrides back in if this is going to be a widespread problem, but at some point it's got to go. If it helps, I could push ahead on supporting inline priority() in rules... ;-) (See http://dirtsimple.org/2010/08/simplifying-prioritized-methods-in-peak.html for details.) > > -- Christoph -- You received this message because you are subscribed to the Google Groups "TurboGears" group.
