Many other existing libraries would be in the same boat - backwards compatibility would be an insurmountable barrier to using enums, but they could use named values.

I like the idea of named values, but to be clear about enums: if they are int-based (like True and False are) and don't mess with the math operations (like True and False don't) then we could use them with impunity:

True + False = 1 os.SEEK_CUR * 3 = 3 (assuming, of course, that os.SEEK_CUR == 1)

P.S. Has the irrevokable decision been made that enums will not be int based? If so, I'll stop bringing up this point -- I'm starting to bore myself with it.
