OO in five lines of Lua

[Eduardo Ochs <eduardoochs@...>]

Hi list,

I just added lots of documentation, including box diagrams and a

detailed example of use, to the OO mechanism that I've been using for

years, whose main part is just these these five lines of Lua code:

  Class = {

      type   = "Class",

      __call = function (class, o) return setmetatable(o, class) end,

    }

  setmetatable(Class, Class)

The code and the comments are here:

  http://angg.twu.net/LATEX/dednat6/eoo.lua      (original)

I guess that most people here will find it almost offensibly simple

but I have hope that some people will find the box diagrams and the

reduction diagrams in its documentation inspiring... maybe even to the

point of creating box diagrams for some of the OOs here:
