Nope. We should maintain consistency over time in the meanings of the
functions. It is not a decent idea to have the next RnRS standard
specify addition in a way which is fundamentally incompatible with its
I have no objection to a (with ...) wrapper which can encapsulate the
new behavior if you want.
