If the re flags were implemented as instances of object instead of int,
then misuse of them as int args would be excepted.  I don't know if such a 
change would otherwise cause a problem.

I wonder whether a subclass of object (EnumSet?) that allowed for 
initialization with a better string representation and that disabled order 
comparisons would fill the bill for unordered enum.

As Steven Bethard also noted, there seem to be a need for two Enum 
subclasses:
EnumSet and EnumSeq.
