---------------------------------
    Description: To enable efficient implementation of select operations such 
as "asList", it is helpful to be able to extract, efficiently (depending on the 
underlying iterators and indexes), an array with all the elements of the 
iteration. Implement this as a "LowLevelIterator" additional method, in various 
ways for all the varieties of iterators.  (was: To enable efficient 
implementation of select operations such as "asList", it is helpful to be able
