That's only because you allowed either TRUE, or FALSE, but no alternatives. All the programming language I used does not deal with direct memory management. Therefore in reality, most of my collection removal functions return an Object, therefore if the Object is found and to be removed from the collection, this object will be returned, if nothing is found, null will returned. LOL

Perhaps that's why in java, when local variables from the methods are being used by anonymous inner classes, it must be declared final.;P
