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.

Properties in the sense of getters and setters yes. All the pieces
are out there, but a framework that does it all could suffer in
performance (for instance, you need a special __index to handle
properties, which would also have to look up plain-jane methods). In
general this is probably premature anxiety.
