Ok, great!

However, none of the variants of zip, including all the three 
policies, fulfills my needs in

     assert(commonPrefixLength([1, 2, 3, 10],
                               [1, 2, 3]), 3);

which fails because

      commonPrefixLength([1, 2, 3, 10],
                         [1, 2, 3])

evaluates to -1.

This seems like a serious limitation that should be realized in 
yet another policy.
