Hi
I'd like to repeat an array along a new axis (like broadcast):
In [8]: a
Out[8]:
array([[0, 1, 2],

In [9]: b=repeat(a[None,...], 3, axis=0)
In [10]: b
Out[10]:
array([[[0, 1, 2],
[3, 4, 5]],
[[0, 1, 2],

It's deliberately unpublicized because you can cause segfaults if you
get your math wrong. But once you get your math right and can wrap
