        "scalar product"
        SYNTAX: X = scalar(v1,v2)

        v1 and v2 are vectors of the same length over Z, Q, Z/mZ, 
        GF(p^n) (where p is a prime), over a number field, over 
        polynomials over these structures or over rational functions.

        The euclidian scalar product <v1, v2> of v1 and v2 is assigned
        to X.


        Example 1: (correct)

                scalar({1/x, 2, 3}, {x/(y + 1), y, 1/2})


        Example 2: (incorrect)

                scalar({1, 2}, {1})
