PEP 354: Enumerations in Python

[Tim Chase]

Just a couple thoughts:

> An enumeration is an exclusive set of symbolic names bound
> to arbitrary unique values.  

Uniqueness imposes an odd constraint that you can't have 
synonyms in the set:

 >>> shades = enum({white:100, grey:50, gray:50, black:0})

Not a bad thing, as it would then have interesting results 
upon iterating (would the above example have three or four 
passes through the iteration loop?), but there could be some 
handy uses for enums containing duplicates.

 >     >>> Grades = enum('A', 'B', 'C', 'D', 'F')

This produces the counter-intuitive result of

	>>> Grades.A > Grades.B
	False

Sure, one can bung with it and create the set of grades 
backwards, but then iteration becomes weird.  Perhaps the 
ability to override the comparitor?
