COLLECT-FN TYPE INIT FUNCTION &rest SERIES-INPUTS                [Function]

    Package
    series

    DESCRIPTION

The higher-order function COLLECT-FN supports the general concept of
collecting.  It is identical to COLLECTING-FN except that it only returns
the last element of each series computed.  If there are no elements in
these series, the values returned by INIT are passed on directly as the
output of COLLECT-FN.

(COLLECT-FN 'INTEGER #'(LAMBDA () 0) #'+ #Z(1 2 3)) => 6 
(COLLECT-FN 'INTEGER #'(LAMBDA () 0) #'+ #Z()) => 0
