[Squeakland] Copy an object programmatically.

[Alan Kay]

Also consider that you can put objects into a playfield both by hand and by 
program and clear the playfield.

I usually put my seed object into a separate little playfield before doing 
this.

One way to look at this is that the playfields act as variables for single 
objects and sets of objects. (If you put 0 at center of a playfield and 
drop in a player, then you have a very nice visible representation of a 
vector -- and there is a vector arithmetic trait that you can turn on, etc.)

Cheers,

Alan
