I am used to simulate the indexed access to any object during plugin simulation.

	private
	getObject setObject:

	accessing	top
	at: Primitive. Assumes receiver is indexable. Answer the value of an indexable element in the receiver. Fail if the argument index is not an Integer or is out of bounds. Essential. See Object documentation whatIsAPrimitive.
	at:put: Primitive. Assumes receiver is indexable. Store the argument value in the indexable element of the receiver indicated by index. Fail if the index is not an Integer or is out of bounds. Or fail if the value is not of the right type for this kind of collection. Answer the value that was stored. Essential. See Object documentation whatIsAPrimitive.
