In this case, I tend to agree that the behaviour is unexpected.  In
some cases, like with sort, however, I think the difference in
behaviour is useful:

In [1]: import numpy as N

In [2]: x = N.array([3,2,1,2])

In [3]: N.sort(x) # Don't tell Guido!
Out[3]: array([1, 2, 2, 3])

In [4]: x
Out[4]: array([3, 2, 1, 2])

In [5]: x.sort()

In [6]: x
Out[6]: array([1, 2, 2, 3])
