! \begin{funcdesc}{zip}{seq1, \moreargs}
    This function returns a list of tuples, where the \var{i}-th tuple contains
!   the \var{i}-th element from each of the argument sequences.  At
!   least one sequence is required, otherwise a \exception{TypeError} is
!   raised.  The returned list is truncated in length to the length of
    the shortest argument sequence.  When there are multiple argument
    sequences which are all of the same length, \function{zip()} is
    similar to \function{map()} with an initial argument of \code{None}.
    With a single sequence argument, it returns a list of 1-tuples.
