There's an implementation of the third way in
http://lua-users.org/wiki/SimpleLuaClasses,
showing how inheritance etc works.  There are some interesting
trade-offs, but it definitely makes sense to have a metatable
corresponding to the 'class' object of other languages like Smalltalk
and Python - that is, a metatable shared by all instances of that
class type.
