Implicit vectorization

Why did Mathsoft (after version 7)expand the implicit vectorization to include the square of a vector?

Now I have to include the absolute operator or explicitly call out the dot product to obtain the correct result of a scalar in standard "book" formulas.

I would prefer to have the presence of the vectorize operator to clarify my intent.

Implicit vectorization

I've never seen v^{2} used to refer to the dot product of a vector v with itself. I believe v*v, or v^{T} v, or |v|^{2} are far more standard.

In the same way, given a square matrix M, the notation M^{2} doesn't refer to M^{T} M.
