The cited page says:

	A system, method and computer-readable medium support the use
	of a single operator that allows a comparison of two variables
	to determine if the two variables point to the same location
	in memory. 

which does not seem to me the same as a comparison operator.

Isn't this a capability for resolving aliasing issues that do not
arise when your language is Ada ?
