A SingletonIterator is an implementation of the Iterator interface for singleton values. This allows 'foreach' to be used with arbitrary objects, or even primitive values. The effect of iterating over a singleton value with 'foreach' using this iterator is simply to invoke the loop once with the loop variable set to the singleton value.
