I woul like to write some classes (to get some OO and inheritance),

Tomas demonstrated something a while back which elegantly leverage
Lua's built-in module system:
http://lua-users.org/lists/lua-l/2006-03/msg00336.html
Something along these lines:
local function extends( aSuper )
return function( aClass )
setmetatable( aClass, aSuper )
aClass.__index = aClass
aClass.self = aClass
aClass.super = aSuper
return aClass
end
end
local class = module
class( 'Object', extends(), package.seeall )
class( 'MyObject', extends( Object ) )
