Glyph, thanks for the input. I mentioned Twisted because in its code I
found a number of places with simple string enumerations used to represent
state. I was not aware of twisted.python.constants, but it doesn't appear
that this module is used at least in the places I checked.
In general, many protocols have some "state" instance var that's usually
just a string, using either predefined constants or direct string literals.
