exports.sigh = function(bool, cb) {
        cb(null, false);
};

The filter function does get fired off, but the bot never replies with anything.

For the sake of completion, we do have another system that might work… but it is for managing conversation state/flow.

+ __start__
- match here {id=123, bool=true,   str="string"  }

%% (bool == true)
  + boo ya
  - YES

%% (id == 123)
- winning

I think the custom function should return true if you want to see the reply, and false if you want to filter it out, though I may be going crazy. Maybe it should be the other way around?
