Wrapping a ndarray

test_wrap.py

import numpy as np

class C(object):

    def __init__(self, value):
        self.value = value

    def __getattr__(self, name):
        return getattr(self.value, name)

c = C(np.arange(1, 10))
an = np.asanyarray(c)
ar = np.asarray(c)

print(type(c), c)
print(type(an), an)
print(type(ar), ar)
