That is indeed the best option. I should have noticed that array
operation was equivalent to a product.

By the way, for cases when operands must be transposed before the
product, there is the matrix_multiply() function, which has keywords
to specify that one or both operands must be transposed, to save the
memory and time that would be consumed by transposing large things.
