Bill, at the risk of appearing to support a different model, or of appearing to be attacking Paella (which at this point I'm not ready to do, one way or another), you forgot to include possibility (d) in your message, namely the possibility that while the proposal may satisfy (a), (b) and (c) entirely, it has undesirable side effects (which is what I read in Mette's undeconstructed critique) Eduardo Burcham, Bill wrote: > It sure is good to have more experts evaluating our proposals.
