 /**
 23  
  * This class has predefined instances that stand for OGNL's special "dynamic subscripts" for getting at the first,
 24  
  * middle, or last elements of a list. In OGNL expressions, these subscripts look like special kinds of array indexes:
 25  
  * [^] means the first element, [$] means the last, [|] means the middle, and [*] means the whole list.
