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)
