Did we actually vote to make display terminating? I thought that we only voted
on the behavior of write, which is different than display. Making write
terminate by default is IMO the only sane choice, but the behavior of display
is quite a different matter, and I know of fewer implementations that take the
terminating display approach when dealing with cycles compared to terminating
