Weakened versions of it definitely hold true for programming languages. Try writing software to solve the same non-trivial problem in several different programming languages, and this will quickly become apparent.

I did this, over the past several months, in Python, Haskell, JavaScript, and C. The Python and JavaScript versions felt pretty similar, but Haskell and C felt unique. If I weren't so busy right now, I'd re-write it in Lisp. I'm pretty sure it would fit naturally with Lisp.
