This 'works for me' attitude is completely unrelated to Lisp. Ever worked in a Java team where some guy constantly checks in code which works for him? I've seen that. He still wanted to check in untested code.
Heh. A friend of mine contracted at a place where two programmers had a long-running feud. Each would check in code that wouldn't compile against the other's. One would comment out the other guy's incompatible code and check in his changes over top of it; then the other would simply uncomment his own code back in, comment out the first guy's stuff, and check in his latest work that way. They alternated this way for months.
