Thanks, Bart. So Tony, it looks like RFC 88, because of its tight coupling
of exception and failure handling, needs to address the issue of "do FILE"
that Bart mentions can set $@. This is an issue that results solely from the
coupling of exception and failure handling, not from the syntax and semantics
of exception handling, so RFC 119 is unaffected.
