Will stick in my oar (warning: bikeshed issue).

I'm totally accustomed to short-circuit boolean ops and was somewhat
disappointed on seeing Erlang's initial ones not do so. Isn't the
biggest win with short-circuit eval that it becomes easier to code two
tests, for which the second makes sense only when the first has a
certain outcome - for example 1) is x nonzero? 2) something about
foo/x.


Which reminds me, I wish Erlang had elsif, or cond. Did anything come
of http://www.bluetail.com/~rv/Erlang-spec/Proposals/cond.shtml?
