Hi All,
Is there a metaclass-y way I could cause the following:
class TheParser(Parser):
def handle_ARecord(self):
pass
def handle_ARecord(self):
pass
...to raise an exception as a result of the 'handle_ARecord' name being
reused?
cheers,
Chris

In my application, I make use of the Borg idiom, invented by Alex
Martelli.
class Borg(object):
'''Borg Idiom, from the Python Cookbook, 2nd Edition, p:273
Derive a class form this; all instances of that class will share
the
same state, provided that they don't override __new__; other

There are many resources for metaclasses on the Net.
There was a Wiki page on www.python.org about them,
but I don't find it now. So, I will refer you to the links
I have handy:
http://www-106.ibm.com/developerworks/linux/library/l-pymeta.html
http://www-128.ibm.com/developerworks/linux/library/l-
When I try to learn metaclass of python by article at this place:
http://www.python.org/2.2/descrintro.html#metaclasses,
I changed the autosuper example a little as below:
class autosuper(type):
def __init__(cls,name,bases,dict):
super(autosuper,cls).__init__(name,bases,dict)
