"Code is also always data! Does it mean that data is also always code? As crazy as this sounds this very well might be the case." My programming languages professor (a Scheme fanatic) expressed a similar sentiment. I recall, however, someone posting this "programmer hierarchy" recently: http://bc.tech.coop/blog/061226.html http://bc.tech.coop/blog/061226.html I find it funny that the hierarchy has "Lisp programmers" at the top and "people who insist on calling HTML a programming language" on the bottom, yet the people I've seen arguing for the programming language status of HTML are predominantly Lisp programmers.
