Regarding wish lists for ASDF 3, you know where to find the XCVB mailing-list and XCVB's TODO file when I need them.
And while I agree that manually converting ASDF systems that can't be automatically converted is not always an option, XCVB lets you use ASDF systems as is, and could be modified to mix-and-match XCVB builds and ASDF systems even more easily than now.
In other words, I think that supporting ASDF is important, but ultimately an evolutionary dead-end.
[ François-René ÐVB Rideau | Reflection&Cybernethics | http://fare.tunes.org ] Government's view of the economy could be summed up in a few short phrases : If it moves, tax it. If it keeps moving, regulate it. And if it stops moving, subsidize it. — Ronald Reagan (1986)
