Yes, my experience is mainly just performing. I haven't done any composition. Maybe if I had, I would've come up with some different analogies. I think the analogy to playing music still works, though. You iterate on a piece by practicing it repeatedly, "adding features" (improving technique), "fixing bugs" (smoothing out passages where you often make mistakes), "polishing the code" (intonation, ornamentation etc). That being said, maybe I should've picked a different title--the analogy to musicians was a source of inspiration for me but isn't really the meat of the idea, I think.
