how about a generic join ? (not as fast as your function approach, i think)
join = function(...)
 local t1 = arg -- {...} for 5.1
 return setmetatable({},
 {
 __index = function(t, k)
 for tt,i in ipairs(t1) do
 local ret = tt[k]
 if (ret~=nil) then return ret end
 end
 error("Not Found" .. k )
 end;
 -- Skip __newindex for clarity.
 }
end
