Reliable comparison for numpy.ndarray

numpy.ndarray (as of 1.5.0.dev) fails to compare tuples in array of dtype object, e.g.

>>> import numpy as np; a=np.array([1, (0,1)], dtype=object); print a == (0,1),  a[1] == (0,1)
[False False] True

This function checks if dtype is object and just does list comprehension in that case
