But this way exists: (?P=startquote) is what you want. To me \g is an
exception, and frankly I did not know about it before this bug report.
I agree that the following sentence could be better structured:
"""
For example, if the pattern is (?P<id>[a-zA-Z_]\w*), the group can be
referenced by its name in arguments to methods of match objects, such as
m.group('id') or m.end('id'), and also by name in the regular expression itself
(using (?P=id)) and replacement text given to .sub() (using \g<id>).
"""
It probably needs to be split into several pieces, contributions are welcome.
