Maybe I am misunderstanding what you are saying -- I think this should
also throw.  I think the rule should be that any attempt to access any
"invalid" contents of a value, for purposes of computation, should throw
an exception.  I say "purposes of computation" because printing must
explicitly be excluded here.  I think this rule applies to both forms of
"invalid" -- both optimized-out and unavailable.
