Hi all,
On the Perl 6 language list, Raphael Descamps posted a link to a paper
explaining how to implement stateful traits
(http://scg.unibe.ch/archive/papers/Berg07eStatefulTraits.pdf). One of the
authors of that paper worked on the original traits paper and the research
appears solid.

The methods are not semantically equivalent, so I had two expectations,
possibly due to

Same as #2, I agree with you, but until we have first class role
attributes and can calculate the methods they will create at
composition time, we won't be able to fix this.
I expect that people will have different views, but that's OK. Have
fun with that.
Well not me, except
Is there a way to tell which attributes come from role? I can't think of
a good way of doing this besides from changing attributes names in some
way. Using prefix for example..

Maybe you want a trait for your attributes that

Yes, I understand the problem. That's why I suggested a role for your
attribute class so that you can say e.g.
