I guess Scheme's exactness differs from this proposal.
Scheme's exactness is orthogonal to the type.  Actually, the spec of
Scheme allows an "inexact integer" and "exact real."
So it makes no sense to quote Scheme.

But I don't mean that I'm against the proposal.  I think the proposal
is fine even if it is different from Scheme's.
