These have been there for a while, but I recently added a couple of

It wasn't removed, I thought to deprecate it. Owing to your response
and the fact that others seem to use c_ quite a bit, I've kept it as a
short hand for
r_['1,2,0', ...]
This means that arrays will be concatenated along the 1st axis after
being up-graded to (at-least) 2-dimensional arrays with 1's placed at
the end of the new shape.
Thus,
c_[[1,2,3],[4,5,6]
produces
array([[1, 4],
[2, 5],
[3, 6]])
This is a bit different if you were using c_ when you should have been
using r_.
