Ok, I will un-warnock myself here :)
As of r5674 in the Pugs tree, the Perl6::MetaModel now supports all the
A12 dispatch orders.
:canonical # canonical dispatch order
:ascendant # most-derived first, like destruction order
:descendant # least-derived first, like construction order
:preorder # like Perl 5 dispatch
:breadth # like multimethod dispatch
For :descendant I just did a reverse of the :ascendant order. I am not
sure that is truly sane or not, but it seemed to make sense to me.
And after some discussion on #perl6 I decided to make 'C3' the
algorithm of choice for the :ascendant ordering, and also to make
:ascendant the :canonical ordering (since it makes MI sane, I mean how
could you go wrong).
Of course all this can change if @Larry decides differently :)
Anyway, back to $work :)
