This argument might have worked a year or two ago when we handn't all been around the entire solution space multiple times...but we have. We know now that most of the options involve some tradeoff that is, in some way, distasteful...including leaning on literal syntaxes when what you really want is a class. So we need to disallow this argument unless it's backed up with a *specific* future-compat critique.

Seconded. We've already walked back a loooong way from the proposals that Bob, Peter, Arv, and I made a year+ ago, and traits as the composition mechanism seem very far off. But nothing gets off the ground without classes. We need this, and we need it *stat*.
