About traits I was thinking to implement the protocol we designed

what's that?
I would like to define some tests also to cover that CM are really
duplicated.
btw., I'm in the process of making http://code.google.com/p/pharo/issues/detail?id=167
work correctly...
why
It was broken?
that is, I'm looking forward for your test ;)
Yes I should really write something.... (fixig again the floor). I
hope to get done after the week end.
something like...
=============================================
A method belong to a trait or a class. how do we query such belonging.
T1
c
Class A
foo
uses: T1 + alias T1>>c = c2
(A>>c2) selector -> c2
(A>>c) selector -> c
(T>>c) selector -> c
(A>>foo) class -> A
(A>>c2) class -> A
(A>>c) class -> A
***(T1>>c) class -> nil or T1 ? **
(A>>foo) trait -> nil
(T1>>c2) trait -> Exception
(T1>>c) trait -> T1
(A>>c) trait -> T1
=============================================
T1
c
Class A
foo
uses: T1 + alias T1>>c = c2
Class B
uses: T1
(A>>c2) selector -> c2
(A>>c) selector -> c
(B>>c) selector -> c
(T>>c) selector -> c
(A>>foo) class -> A
(A>>c2) class -> A
(A>>c) class -> A
(B>>c) class -> B
(A>>foo) trait -> nil
(T1>>c2) trait -> Exception
(T1>>c) trait -> T1
(B>>c) trait -> T1
(A>>c) trait -> T1
=============================================
T1
c
c1
T2
c
c2
uses: T1
Class A
foo
uses: T2
(A>>c2) selector -> c2
(A>>c) selector -> c
(T2>>c) selector -> c
(T1>>c) selector -> c
(A>>foo) class -> A
(A>>c2) class -> A
(A>>c) class -> A
(A>>c1) class -> A
(T1>>c1) class -> ???? T1 or nil
(T2>>c1)
(T2>>c2) class -> ???? T2 or nil
(A>>foo) trait -> nil
(A>>c2) trait -> T2
(A>>c) trait -> T2
(A>>c1) trait -> T2 ***** since it is flat
(T1>>c1) trait -> ???? T1 or nil
(T2>>c1) trait
(T2>>c2) trait -> ???? T2 or nil
origin = definingClassOrTrait
(A>>foo) origin -> A
(A>>c2) origin -> T2
(A>>c1) origin -> T1
(A>>c) origin -> T2 *****
(T1>>c) origin -> T1
(T1>>c1) origin -> T1
The origin is the method that you changed (and not override) when you
want to change a method in the flat view.
