Yep, thought so too..

Slightly modified:

  printf("luaI_registerlocalvar() %s:%d; ", __FILE__, __LINE__ );
  { int i; for (i=0; i<=fs->nlocvars; i++)
    printf("%d: %s  ", i, getstr(f->locvars[i].varname)); printf("\r\n"); }


Got this:

        local test = {}
        test.__index = test

        function test:foo()
                return self[1]
        end

        function test:func( idx )

              local a, b, c = 1, 2, { foo = idx }
                if idx.foo then return false end
                return self:foo() + idx
        end

        function new_test()
                return setmetatable( { 1, 2, 3, 4, 5 }, test )
        end
end

I leave any conclusions too you..
