Actually it couldn't, except for the special case of
concatenating along the first axis. The concatenate()
function allows specifying an axis.
There's also the problem that applying a concatenation
operator to a numpy array of Python sequences would be
ambiguous -- does it mean concatenating the arrays, or
elementwise concatenation of their contents?
