Correction for msg63584: the old/new style difference example should read
"""
class x:
pass
class y(x):
pass
try:
raise y
except y:
print "b"
except:
print "a"
"""
As written it prints 'b', but with __metaclass__ = type, it prints 'a'.
In msg63584 I got 'a' and 'b' mixed up.
On python-dev, Guido responded that the result should be the same
regardless of the metaclass:
