Please don't add this. I have my own tuple parametric class. In fact it is easy to do. http://code.google.com/p/bookjar-utils/source/browse/BookJar-utils/src/util/Tuples.java
However i never use it anymore. It is easy to do & use, but really stupid since the names (first, second, third...) are so generic... and it has no behavior. Invariably i have to replace it by a more domain appropriate class with real names & methods. A real tuple (where the names don't mater...) might be usable generally, but not a tuple like normal type.
