I would prefer
class Foo(metaclass=namedtuple, fields = 'x,y,z'):
...
which while slightly more verbose, does not lie about what namedtuple is -
a factory of classes. This, however is completely orthogonal to the issue
of performance. As I mentioned in my previous post, namedtuple metaclass
above can be a simple function:
def namedtuple(name, bases, attrs, fields=()):
# Override __init_subclass__ for Python 3.6
return collections.namedtuple(name, fields)
