hmm, I don't get the warm fuzzy feeling I got from
reading A1. I was hoping that with stronger typing we
would be able to do away to $ @ and % to instroduce
variables. That doesn't look like it's going to happen.
I like the idea of being able to interpolate scalars
and lists into strings (to whit: "foo $(scalar exp)" and
"foo @(list exp)".
On the other hand, replacing __END__ with =begin END
strikes me as being akin to using the Start menu in Windows
to shut down the machine.
