Umm..sorry, this particular argument doesn't work. The proposed optimisation only improves the speed of comparing an object to itself - not the most common operation in collection work. Operations that speed up determining when two objects are NOT equal would help much more. [1] I still think the original patch is relevant though (just not this point). [1] eg org.apache.commons.collections.map.IdentityMap, but this relies on unique objects for keys rather than just trying to optimise for them.
