Allin,
I was playing with the square() function in the list context. It would be
very useful if one could specify the equivalent of the --cross option in
the function, as in
list foo = x1 x2 x3
list foosq = square(foo,1) # x-products
as opposed to
list foo = x1 x2 x3
list foosq = square(foo,0) # no x-products
I've been trying to find the place in the source where to make some
changes, but I gave up after the umpteenth Alt-.
Any advice?
