Metaclasses and new-style classes

[jepler at unpythonic.net]

This may be a limitation Zope imposes.

I wrote this program:
#-----------------------------------------------------------------------
class M(type):
	def __new__(*args):
		print "new M", args

class T(object):
	__metaclass__ = M
#-----------------------------------------------------------------------

Running it prints
new M (<class '__main__.M'>, 'T', (<type 'object'>,),
	{'__module__': '__main__', '__metaclass__': <class '__main__.M'>})
... so you can see that the __metaclass__ mechanism works just fine with
new-style objects in plain Python.
