This would work:
footer => sub { "$From - $To" }
except there's no way of setting the $From and $To variables as each page is
formatted. I don't think C<format> by itself is the right solution for this
problem, unless I add some kind of weird monitoring option.
That's probably beyond the scope of this RFC at present.

I have a good idea for this. I'll add it to the next version of the RFC.
