listless
     
         In {functional programming}, a property of a
        {function} which allows it to be combined with other functions
        in a way that eliminates intermediate data structures,
        especially lists.
     
        {Phil Wadler}'s thesis gives the conditions for a function to
        be in listless form: each input list is traversed only once,
        one element at a time, from left to right.  Each output list
        is generated once, one element at a time, from left to right.
        No other lists are generated or traversed.
     
        Not all functions can be expressed in listless form
        (e.g. reverse).
