Or is it in llimits.h because it's supposed to be changed very rarely? A second point: does "should not be larger than 255" mean there is no way to disable it and restore the previous behavior? Maybe "0=all strings are interned" could be useful in case some program had trouble with the new system (e.g. I can think of some sort of text processing, such as a translation helper that uses chunks of already translated text as table indexes). Assuming no underlying change or new optimization prevents this, of course.
Indeed. I'm pretty sure that I use very long strings as index all over the place. But does this patch indeed prevent long strings to be unique indices? For me the interning of strings is one of the charms of Lua.
