New submission from Jim Jewett <jimjjew...@gmail.com>:
collections.namedtuple raises a ValueError if any of the field names are not
valid identifiers, or are duplicates.
It does not normalize the identifiers when checking for duplicates.
(Similar issue with the typename)
>>> namedtuple("dup_fields", ["a", "a"])
Traceback (most recent call last):
File "<pyshell#23>", line 1, in <module>
namedtuple("dup_fields", ["a", "a"])
File "C:\python32\lib\collections.py", line 345, in namedtuple
raise ValueError('Encountered duplicate field name: %r' % name)
ValueError: Encountered duplicate field name: 'a'
>>> namedtuple("nfk_tester", ["a", "ª"])

>>> namedtuple("justª", "ª")

result = namespace[typename]
KeyError: 'justª'
