They're getting buffered. Try this:

  (as/pipe (as/map< (fn [x] (print "<") (flush) x) source)
           (as/map> (fn [x] (print ">") (flush) x) sink))

Those calls to flush will make sure it prints those characters
immediately. Then you'll see the output you're expecting.

I can't help you with whether this is the right way to do things,
unfortunately, as I've only had very limited experience with core.async.
