	It typically for people doing long paths.

	elem.getChild("foo").getChild("bar").getChild("baz);

	You can wrap that with a single try/catch for the
	entire chain.  Otherwise, you have to wrap each
	getChild() call with an "if (elem != null)".  Which
	turns into a lot of typing.

	Also, Exception handling in Java isn't heavy-weight.
	It's computationally similar to a normal return, with
	an 'isAnException' flag set.  Remember that Java isn't
	compiled C++ code.
