By putting "?" into M or by implementing get function to access upvalue(s).
Sometimes implementing set/get pair for every piece of data is worth it anyway
(e. g., in widget system), sometimes it's just an overhead.

Several upvalues may be packed into single table like:
   M.private = {a = b, c = d, e = f}
or accessed by single function:
   function M.get_stuff ()
       return b, d, f
   end
