maplist

(maplist function list)

Like mapcar, but function is applied to successive cdrs (tails) of list rather than to its elements: first the whole list, then its rest, and so on down to the last single-element tail. Returns a new list of the results. Single-list form only.

The argument must be a list (nil, the empty list, is accepted); passing a non-list such as a string signals an error rather than silently returning nil. Use map to map over a string or vector.
