The standard is just plain not clear here.  There's nothing that says

the subsequent use, assuming that conversion to a value outside the

But that last assumption isn't correct, is it?  I don't see how that's
consistent with 7.2p9: it talks about "the resulting enumeration
value", which should surely mean that a value outside the enum range
_isn't_ permitted.

Grrr... It _is_ permitted. The standard is perfectly clean on this issue.
