I don't agree that it would be so bad.  One implementation is in the field
fullName you'd have a wrapper object whose "function" event is set to
something like:

    function wrapper(obj, ...)
        local oldtable = globals(obj.locals)
        local val = call(obj.realfunc, arg)
        globals(oldtable)
        return val
    end

This function could be implemented from C.

The thing is, you can do much more with this than just eliminate the self's
in your classes.  You could do a mean module system, closures, namespaces...
