[Since %u is used for unsigned integers in printf, I would find it confusing. Note that in the 2006 thread I cited earlier, we discussed other possible modifiers including %m %t and %y (for metatable tostring and stringifY).]

Is there any reason that you would not want string.format to apply tostring to a userdata provided for a %s argument?
