Your comment is really quite interesting. Thanks! What you're saying all sounds plausible to me.

I note that, while different circles may call for "purity" (fans of, e.g., Unix, Lisp, or Haskell), I think honestly pursuing the purity of writing programs to achieve one's goals means rejecting dogmatism and accepting pragmatism. Adherence to beliefs is fine if, and only if, the beliefs are fundamentally justified....
