for f in a b { echo $f; }               # invokes shell command echo
for f in a b ( find-file f )            # invokes Lisp command

It's quite cool, actually, though the syntax is not very Bourne-ish.

How to do two Lisp commands?  Hm.  Oh.  Very interesting.  Compare:

for f in a b (progn (message f) (sit-for 1))
for f in a b { (message f); sleep 1 }

It changes the behavior of `message'!
