/**
 * Extension methods enable you to "add" methods to existing types without creating a new derived type, recompiling, or
 * otherwise modifying the original type. Extension methods are a special kind of static method, but they are called as
 * if they were instance methods on the extended type.
 * 
 * Before:
 * 
 * 
 * @ExtensionMethod({ java.util.Arrays.class })
 * class Example {
 * 	private void example() {
 * 		long[] values = new long[] { 2, 5, 7, 9 };
 * 		values.copyOf(3).sort();
 * 	}
 * }
 * 
 * 
 * After:
 * 
 *  * class Example {
 * 	private void example() {
 * 		long[] values = new long[] { 2, 5, 7, 9 };
 * 		java.util.Arrays.sort(java.util.Arrays.copyOf(values, 3));
 * 	}
 * }
