The thing is, the more I think about it, the more I think the simple-to-follow argument says un-escaped literal '{' should not become fatal until _all_ cases of interest can be made fatal. Doing it in two (currently) stages means, at least, explaining to people that they are allowed (with a warning) to write /^{/, but /\A{/ is fatal -- and the same for however many other cases there are.
Or have I misunderstood?
