This sort of thing has been discussed before. It seems fairly clear to
me that any of these variations represents a performance tradeoff: some
cases will get better and some will get worse. I think we are not going
to get far unless we can agree on a set of benchmark cases that we'll
use to decide whether the tradeoff is a win or not. How can we arrive
at that?
