Considering we still have * for Whatever, I don't see any problem with
letting ** still mean MultiDim of Whatever.  In fact, we've made it easier
now.  I was deleting it from S03 only because it's not an argumentless operator
anymore, but a lowly term.  Probably about time to revisit S09 again...

Is there any new format to do the equivalent of C<@foo[1;**;5]>, or is
that impossible nowadays?

English not being executable line noise, you can't use "either" to force
a scalar into list context.
