The newly added shlex.punctuation_chars is special compared to the other public instance variables: It can ONLY be used when constructing a shlex instance, unlike other public instance variables, such as commenters, which can ONLY be set later.

>>> s = shlex.shlex('abc // def')
>>> s.commenters = '/'
>>> list(s)
['abc', '', '']

>>> s = shlex.shlex('abc // def', punctuation_chars = '/')
>>> list(s)
['abc', '//', 'def']

However, setting punctuation_chars later shows this rather useless error message:

>>> s = shlex.shlex('abc // def')
>>> s.punctuation_chars = '/'
>>> list(s)
