syntactically, the underlying operator is always applied with its
own associativity, just as the corresponding reduce operator would do.
+The zip operation terminates when either of its lists terminates.
+(Do not use C<Zeq> or C<Z==> to compare two arrays, for instance,
+unless you want to know if one array is a prefix of the other.
+Use C<»eq«> or C<»==«> for that. Or better, just use C<eqv>.)
Note that, unlike the C<X> operator, all the terms of a C<Z> operator
may reasonably be infinite lists, since zipping is lazy.
