One clarification about this quote is in order though. If you read through
the thread, you'll see that Rich was *not* saying this in the sense of, "{1
2, 1 3} is an error, and we need to throw an exception." He was actually
calling it an error in the sense of defending his desire to do no check at
all. In many places, Clojure exhibits a garbage-in-garbage-out philosophy,
and this is actually what he was advocating. He was just saying that if
someone types {1 2, 1 3}, it's their fault, and they deserve whatever bad
things come out of it.
