Very useful; thank you. One more request: could you provide a few
multidimensional examples? For instance:
(1, 2, 3; 4, 5, 6) «+» (1, 2; 3, 4; 5, 6)
My gut instinct is that this would be equivalent to:
(1, 2, 3; 4, 5, 6; 1, 2, 3) «+» (1, 2; 3, 4; 5, 6) # lhs dwimmery
in the first dimension
...which in turn would be equivalent to:
(1, 2, 3; 4, 5, 6; 1, 2, 3) «+» (1, 2, 1; 3, 4, 3; 5, 6, 5) # rhs
dwimmery in the second dimension
Or:
(2, 4, 4; 7, 9, 9; 6, 8, 8)
But I'm not sure. If I'm right, I'd like it confirmed; if I'm wrong,
I want to see what the right way to do it is.
