I do use it.  It makes a lot more sense if you use something like LISP or Clojure because (parens are king).<p>I really enjoy programmer dvorak.  As you say, re-training copy and paste is a bit of a task, but my hands feel far less fatigued typing on dvorak than on Qwerty.  Now I am type-fluent in both due to necessity and public terminals, but prefer to use programmer dvorak.  I really like the numerical layout because there is some rhyme and reason: Left hand from middle out: 91357%, right hand from middle out:   02468` ... so it&#x27;s a lot easier to type numbers because of that break-up.  I don&#x27;t mind having to hit shift for numbers because it makes for faster coding.
