[Numpy-discussion] How to combine a pair of 1D arrays?

Is there a way to combine two 1D arrays with the same size into a 2D
array? It seems like the internal pointers and strides could be
combined. My primary goal is to not make any copies of the data. It
might be doable with a bit of ctypes if there is not a native numpy call.
>>> import numpy as np
>>> a = np.array((1,2,3,4))
>>> b = np.array((11,12,13,14))
>>> c = np.magical_fuse(a, b) # what goes here?
>>> print c.shape
(2, 4)
>>> a == c[0]
True
>>> a[1] = -2
>>> a == c[0]
True
