### 14.1.1. Mapping Functions

Function `EXT:MAPCAP`. The function `EXT:MAPCAP` is like `MAPCAN`, except that it concatenates the resulting lists with `APPEND` instead of `NCONC`:

    (EXT:MAPCAP function x1 ... xn) ≡
    (APPLY #'APPEND (MAPCAR function x1 ... xn))

(Actually a bit more efficient that this would have been.)

Function `EXT:MAPLAP`. The function `EXT:MAPLAP` is like `MAPCON`, except that it concatenates the resulting lists with `APPEND` instead of `NCONC`:

    (EXT:MAPLAP function x1 ... xn) ≡
    (APPLY #'APPEND (MAPLIST function x1 ... xn))

(Actually a bit more efficient that this would have been.)
