Well, the point of an OR'able flag is that the result shows the OR'd 
values in the repr. Raymond suggests using a set of strings where you 
need flag constants. For new apis (so no backwards compatibility 
constraints) where you don't need to use integers (i.e. not wrapping a C 
library) that's a great suggestion:

     flags = {'FOO', 'BAR'}
