I figured out also that you cannot define ACCESS and ASSIGN methods this way, for example, to track field changes in that objects. Programmatic code for ACCESS and ASSIGN could be defined and works only if they already defined in the class used for original object, that you can override them programmatically. When they're not defined, you can define them programmatically, but they do not work as expected.

George Tasker's mention was that you could define a custom object with _Access events on properties that are the same as field names, and these Access events would fire on a GATHER FROM NAME command. Couldn't get the Assign event to fire, though.

If I can find who the originator was from the NG's that started me experimenting with this, I'll try to whip something up.
