Well, in "Python in a Nutshell" Alex Martelli manages to pack the practical
information that lets you work with metaclasses into just four pages,
including a two-page example. You may have s
Thank you Peter, this does the job.
In passing, I have another question: where can I read up more on
metaclasses?

As an supplement to my previous post, please find hereunder a snippet
for my unsuccessful attempt (commented out snippet does not work):
def superTuple(*attribute_names):
nargs = len(attribute_names)
class T(tuple):
def __new__(cls, *args):

A quick check:
>>> class T(tuple):
... class __metaclass__(type):
... x = property(lambda cls: 0)

Hello,
I have got a problem that i can't readily solve.
I want the following:
I want to create a supertuple that behaves both as a tuple and as a
class.
It should do the following:

p=Point(4,7,9)
assert p.x==p[0]
assert p.y==p[1]
assert p.z==
