I assumed that the wrapper type name was "allow_clipping_to_eom"
and that it had a ctor taking a date.  Thus, the expression above
would create an unnamed temporary of type allow_clipping_to_eom
and then some namespace scope operator +() would take an
allow_clipping_to_eom and a typeof(2*months), returning a date.
