Source code in the quackery programming language

  [ this ] is U0

  [ this ] is U1

  [ 0 = iff U0 else U1
    message put bail ] is baz ( n --> )

  [ baz ]              is bar ( n --> )

  [ 2 times

        bailed if
          [ message share 
            U0 oats iff
              [ say "Exception U0 raised." cr
