374 Role conflicts between attributes and methods
376 [15:23] <kolibrie> when class defines method and role defines method, class wins
377 [15:24] <kolibrie> when class 'has' method and role defines method, class wins
378 [15:24] <kolibrie> when class defines method and role 'has' method, role wins
379 [15:24] <kolibrie> when class 'has' method and role 'has' method, role wins
380 [15:24] <kolibrie> which means when class 'has' method and two roles 'has' method, no tiebreak is detected
381 [15:24] <perigrin> this is with role and has declaration in the exact same order in every case?
382 [15:25] <kolibrie> yes
383 [15:25] <perigrin> interesting
384 [15:25] <kolibrie> that's what I thought
385 [15:26] <kolibrie> does that sound like something I should write a test for?
386 [15:27] <perigrin> stevan, ping?
387 [15:27] <perigrin> I'm not sure what the right answer for composition is.
388 [15:27] <perigrin> who should win
389 [15:27] <perigrin> if I were to guess I'd say the class should always win.
390 [15:27] <kolibrie> that would be my guess, but I thought I would ask to make sure
391 [15:29] <stevan> kolibrie: please write a test
392 [15:29] <stevan> I am not exactly sure who should win either,.. but I suspect it is not working correctly right now
393 [15:29] <stevan> I know exactly why it is doing what it is doing though
395 Now I have to decide actually what happens, and how to fix it.
