We talked about it before, but I am almost convinced to add AnyEvent->loop
and AnyEvent->one_event methods on the grounds that, even though they should
not be used inside modules, there is merit in having event-loop independent
main programs (something anyevent was not designed for).

That *might* help people with this common oversight.
