(--map-indexed FORM LIST)

Documentation

Eval FORM for each item in LIST and return the list of results.

Each element of LIST in turn is bound to it and its index within LIST to it-index before evaluating FORM. This is like
--map, but additionally makes it-index available to FORM.

This is the anaphoric counterpart to -map-indexed.
