Named tuples can also be used to emulate enum datatypes. The patch adds
an example to the documentation.

The motivation for this patch is that documenting a single function
adding enum-like capabilities would hopefully eliminate the numerous
"enum" recipies already out there, each handling things a little different.

Fixed example (a * was missing) and committed as r62007. Thanks!

Raymond, is this kind of recipes worth adding to the 'collections' module?
Maybe with the following form:
def enum(*valuenames):
 return namedtuple('Enum', valuenames)(*range(len(valuenames)))

Thanks for asking. This should not go into the collections module.
The concept makes more sense in statically compiled languages. In 
Python, we typically write something like "RED, ORANGE, YELLOW = range
(3)" at the module level. That is faster and still allows prefixing 
using the module name (for example, re.MULTILINE).
