    Apply \var{function} of two arguments cumulatively to the items of
    \var{sequence}, from left to right, so as to reduce the sequence to
!   a single value.  For example,
!   \code{reduce(lambda x, y: x+y, [1, 2, 3, 4, 5])} calculates
!   \code{((((1+2)+3)+4)+5)}.
!   If the optional \var{initializer} is present, it is placed before
!   the items of the sequence in the calculation, and serves as a
!   default when the sequence is empty.
