From: Ken Helias <kenhelias@firemail.de>
All other add functions for lists have the new item as first argument and the
position where it is added as second argument. This was changed for no good
reason in this function and makes using it unnecessary confusing.
The name was changed to let old code generate a compile errors instead of
using the wrong parameter order.
