otherwise if you prefer to have the newline at the bottom of the chain
we could just do 
   console-stream-output ==>
       "~" c-string nl

   target-stream-output ==>
       "@" c-string nl

   log-stream-output ==>
       "&" c-string nl

The first solution is shorter, the second solution is more obvious to
the eye.
