I want to get a letter that is i greater than 'A', 
while iterating over arbitrary iterable.
Imagine something like:

    for i, foo in enumerate(bar):
        print 'Entity %s is %s' % (chr(ord('A') + i), foo)

Since my original posting, I've thought of the following, 
but I don't know if it's better. Separating the ugliness 
of ord() and chr() might just make it harder to understand.

    a = ('hello', 'world', 'foo', 'bar')
    for c, foo in enumerate(a, ord('A')):
        print 'Entity %s is %s' % (chr(c), foo)

I'm iterating over some arbitrary iterator 
and need to generate letter 'indexes' for printing.

I don't have a list of letters from which to pull.

I understand 'hello world'.upper(), but not string.upper[i].
