the first two are so trivial to achieve that it's (IMNSHO) silly to try
to 'standardise'. rolling your own means only think that way when coding.
inheritance is the almost-missing piece, and here is where most people find
themselves doing all kinds of kludges, and/or inefficiencies.
but, at the same time, most of these schemes are interoperable, just because
of using the same syntax.
myself, i've found that sometimes it's nice to think in objects, but i've
never (NEVER) found myself using inheritance when not using C++. why?
simple, because in dynamic languages the polymorphism is so much more
flexible that it's not needed!
if two objects (i seldom use classes) are similar, just reuse the code. no
need to make them fit to a hierarchy, because in a functional language you
can shuffle around methods, or easily setup some delegations, or
even 'aspects' if you want.
that's why i hope there's never a 'blessed' OOP scheme in Lua. just look at
the mess that JS got!
