should ndarray implement __round__ for py3k?
A simple test in python 3:
import numpy as np round(np.arange(10))
Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: type numpy.ndarray doesn't define __round__ method
Here is some additional context: http://bugs.python.org/issue7261

I'd put that in the "would be nice, but not a priority" category.

I implemented this for array scalars already, but forgot about arrays. Anyway, it could be nice to have.

I like the fact that python >= 3.1 returns integers when rounding floats.
