How about a hash table? NewtonScript, JavaScript, and Lua use simple hash
tables for "objects". An object becomes simply a hash table that holds 
both data
and functions. For example:

Dog =
   name = "fido",
   bark = function (self) print("bark") end

To get inheritance add the simple rule:

if table lookup fails and table has a parent name/value pair then 
perform the
lookup on the parent value.
