| #### D.5.2.8 sum_of_powers Procedure from library `chern.lib` (see chern_lib). Usage: sum_of_powers(k, l); k non-negative integer, l list of polynomials Return: polynomial Purpose: computes the sum of k-th powers of the entries of l Note: returns 0 if k is negative Example:
    LIB "chern.lib";
    ring r = 0, (x, y, z), dp;
    list l=x, y, z;
    //sum of 7-th powers of x, y, z
    print( sum_of_powers(7, l) );
    ==> x7+y7+z7
