§ 4.53  - [lslice] Built-InMnemonic aid: lslice for one List SLICEd into another
See also:  [aisort] ,  [append] ,  [asort] ,  [clearl] ,  [cmap] ,  [dlist] ,  [e] ,  [hmap] ,  [isort] ,  [lcc] ,  [lcopy] ,  [lhsort] ,  [list] ,  [ljoin] ,  [llen] ,  [lpop] ,  [lset] ,  [lsplit] ,  [lsub] ,  [ltol]  and  [translate] 
Slices one list into another, or the same, list. sliceSpec can be any of the following, where a, b and c are integers::

 a ------pulls that element out of the list
 a:b ----pulls from a to b-1
 a:b:c --pulls from a to b-1, stepping by c
 :b -----pulls from beginning to b-1
 a: -----pulls from a to end
 ::c ----pulls from beginning to end, stepping by c
 :b:c ---pulls from beginning to b-1, stepping by c
 a::c ---pulls from a to end, stepping by c
Tip: When a slice component a or b is negative, then it refers to a list element relative to the end of the list. When c is negative, the step goes from the end of the list towards the beginning of the list.
