Not applicable?

repeats= could actually be a tuple containing the number of times each
dimension should be repeated. In this case, repeats[-1] should correspond
to the last dimension of a, and any missing dimensions in repeats= 
should default to one. So, axis=-1

-1, same as take()

0, I *think*.

In all cases, the ability to use non-default axes should be preserved.
