t place. This is as opposed to the
thing I was trying to do, which was to use the "P=" syntax in a substitution.

Subject: [Tutor] Example of use of (?P) and (?P=name)
Greetings. While looking into the use of regular expressions in Python, I saw
that it's possible to name match groups using:
(?P...)
and then refer to them using:
(?P=name)
I was able to get this to work in the following, nonsensical, example:
>>> x = 'Free Fri Fro From'
>>>
etattr__ = no_new_attributes(type.__setattr__)
(Beware line breaks introduced by email software.)
Finally, my question: can somebody enlighten me as to how and why the
"custom metaclass",
class __metaclass__(type):
does something useful?
Thanks.
