Yes. It's so easy to forget that.

Now that is mind expanding. If you tried that in C you'd collapse the
universe.
Interpreted .... sure, it can saw off the branch it's sitting on because
there is no
tree. Each command is past when it's past so that must mean that the
address of
first foo ... is there ... yes of course there is, the thing is in
memory ... just aborts
when second foo comes along. It will expect grammatical completion of
first foo
for the sake of etiquette. And when foo calls itself, it calls new foo
which is
not recursive. I am not yet able to snatch the pebble out of your hand,
but that's
a zsh koan.
