Doing so is legitimated by the last paragraph of 6.2.1:
Rational operations such as + should always produce exact
results when given exact arguments. If the operation is unable
to produce an exact result, then it may either report the
violation of an implementation restriction or it may silently
coerce its result to an inexact value.
I'll retest with the Schemes whose implementers we haven't heard from
in a few days, after changes to the test have settled down.
