What's "this" ?

anyway, I think what you want to do is:

__index =
 function(this, aKey)
   return
     function(...)
       return this.forwardInvocation(unpack(arg))
     end
 end

or something along those lines.

In other words, the __index function is simply returning the
value corresponding to anObject.doit, which value should in
this case be a function. That function will be called in
due course.
