Есть ли код Python в стандартной библиотеке Python, который использует имена переменных, которые встроены в тени?

Встроенный я чаще всего тень - это id, так как он настолько полезен, как имя переменной, и встроенный так редко называют в любом случае. Быстрый просмотр в стандартной библиотеке 2.7 показал ряд применений:

aifc.py:            if id == marker[0]:
aifc.py:                id = _read_short(chunk)
aifc.py:            if id == self._markers[i][0]:
aifc.py:            if id == marker[0]:
difflib.py:            id = ' id="%s%s"' % (self._prefix[side],linenum)
difflib.py:            id = ''
nntplib.py:        id = ''
nntplib.py:                id = words[2]
nntplib.py:        resp, nr, id = self.statparse(resp)
pdb.py:            id = idstring[0].strip()
pdb.py:            id = idstring[1].strip()
pdb.py:        if id == '': return failed
platform.py:                id = values[2]
platform.py:    id = ''
platform.py:            id = l[1]
platform.py:        id = _id

Существует множество применений str, list и int также:

xmllib.py:                    str = chr(int(str[1:]))
xmllib.py:                    str = self.entitydefs[str]
xmllib.py:                    str = '&' + str + ';'

uuid.py:            int = long(hex, 16)
uuid.py:            int = long(('%02x'*16) % tuple(map(ord, bytes)), 16)

и есть слишком много file и dir используют, чтобы отправлять...
