If you think of it, collection.namedtuple \*is\* a metaclass. A simple wrapper will make it usable as such:

import collections

def namedtuple(name, bases, attrs, fields=()):

# Override \_\_init\_subclass\_\_ for Python 3.6

return collections.namedtuple(name, fields)

class Foo(metaclass=namedtuple, fields='x,y'):

pass

print(Foo(1, 2)) # ---> Foo(x=1, y=2)
