After all, it's such fun to do our own; sometimes I think this was a lost opportunity. A straightforward metatable-based OOP scheme is maybe a hundred lines of code, which hides the 'uncomfortable' stuff and puts it behind a 'standard' facade. If such a little module were included in the Lua 5.1 distribution (like strict.lua) then perhaps we would not have such fragmentation.
Probably not, but there could be a cost: people would start building around this 'standard' OO and pretty soon our beautiful swiss-army knife of a language could feel cast in concrete and become as unwieldy as, say, Java.
Besides, not everyone needs formal OO (I can usually live without it, for example), so I'd keep such code neither in the distribution nor in a standard library (where it could do great damage by imposing an 'ideological' view), but in an external add-on library. Just as Unicode strings, sockets and other features that can be invaluable to somebody and useless to others.
