For being a pinnacle it is really unsatisfying.  It tells you very little about how or what programs can be composed.  It&#x27;s either trial and error or reading man pages.  In addition every program has to be written to take in anything as there are no constraints.<p>Function composition via types is a much more satisfying take on this problem.  It&#x27;s too bad Unix is regarded as the holy grail of this technique when it barely provides a passable implementation of it.<p>Text just isn&#x27;t a great medium for IPC.
