For most users who are associating objects with turtles this will be a more natural way to refer to methods (& instance variables).
It is possible to switch between different styles of method ownership as follows...
table:put #mop "method-owner" "who" ;; turtle context ownership
table:put #mop "method-owner" "self" ;; NLoops4 ownership
...this can be done at any time to switch between modes but will be reset to the new turtle-context default when #reset-objects is called.
NLoops5 also allows patches to spawn objects.
We are still improving things so please contact us if you have suggestions/comments.
