hyperoperators and multi-dimensional datastructures

Is there a way to target hyperoperators at different axes of a
multi-dimensional array?  This is an attractive feature of
various APL-like languages, viz. e.g. in J:

    a =. 2 5 $ i. 7      - a simple 2-by-5 array
    a
0 1 2 3 4		- like this
5 6 0 1 2


    +/"1 a		- sum reduce over axis 1
10 14
    +/"2 a		- sum reduce over axis 2
5 7 2 4 6
