I rather like this compromise. It provides the desired behaviour of
"always default to the current topic" and so eliminates the confusion
between C<when> and other defaulting constructs. It also maintains the
"$_ is default" concept, which is quite important to people, as earlier
bits of this thread demonstrated.
