To me, "copy" does imply creating a new object.

Also, it is only ever used as argument to another tile. I find the difference to be obvious:

	Holder include Sketch

moves the Sketch into the Holder, whereas

	Holder include Sketch copy

does not affect the Sketch itself, but adds a copy of it. I don't see how adding "new" would clarify this, but I'm happy to be convinced otherwise :)
