Hmm, well, you can view C<redo> as just a C<goto TOP> in disguise,
or as a C<next> that suppresses the "while" check. But I think it's
seldom enough used that it doesn't rate the mindspace of a REDO.
Very few blocks would have multiple C<redo>s, and that's the only
reason you might want a REDO block. In contrast, many blocks have
multiple explicit C<next>s, as well as the implicit "next" of falling
out the bottom of the loop.
