       linsert - Insert elements into a list


       linsert list index ?element element ...?


       This  command produces a new list from list by inserting all of the element arguments just
       before the index'th element of list.  Each element argument will become a separate element
       of  the  new  list.   If  index  is  less than or equal to zero, then the new elements are
       inserted at the beginning of the list, and if index is greater or equal to the  length  of
       list,  it is as if it was end.  As with string index, the index value supports both simple
       index arithmetic and end-relative indexing.

       Subject to the restrictions that indices must refer to locations inside the list and  that
       the  elements  will always be inserted in order, insertions are done so that when index is
       start-relative, the first element will be at that index in the resulting  list,  and  when
       index is end-relative, the last element will be at that index in the resulting list.


       Putting  some values into a list, first indexing from the start and then indexing from the
       end, and then chaining them together:

              set oldList {the fox jumps over the dog}
              set midList [linsert $oldList 1 quick]
              set newList [linsert $midList end-1 lazy]
              # The old lists still exist though...
              set newerList [linsert [linsert $oldList end-1 quick] 1 lazy]
