Hi Adrian,
    what do you mean by "automated bootstrapping"?... I understand what 
it means by itself but not in the context of traits... Could you give us 
an example?
    I haven't look at the Traits implementation but I know it has 
tests... what do they test? do they test the hole implementation? only 
the traits composition?

    Thanks,
    Hernan.
