Description

As far as I can tell Insert is never called by any function in the standard CoCoA packages.

I would like to make the function obsolescent. If that is not acceptable I wuld like to add some comments on the manual page that use of Insert is best avoided (for reasons of efficiency of for no other), and mention using either the function Append or simply assigning to an entry in the list as better alternatives.

C5 differs slightly from C4. In C4 it is possible to Insert an element after the last entry in a list (by specifying position 1+Len(L)); in C5 it is not currently possible because specifying position 1+Len(L) gives a run-time "out of range" error. JAA regards this as a bug in the C5 implementation (at low level) -- it may easy be worked around by modifying the defn of Insert in the file BackwardCompatible.cpkg5
