A counterexample with gethostbyname - a list of proxies. It's not an
error if some or even all proxies in the list are down - one just
connect to the first that's up. So a chain like
proxy_addr = gethostbyname(FIRST) or gethostbyname(SECOND)
would make sense.

Programmers don't die, they just GOSUB without RETURN.
