List/Set.last

Returns the last item of a list. If MyList is a 5-item list "ant;bee;cow;dog;eel":

$MyString = $MyList.last; returns "eel"

List/Set.last(N)

Returns a list of the last N items of a list. With the same list as above:

$MyList2 = $MyList.last(2); returns "dog;eel"

Testing for loop position

This operator can be used to test the current loop state, i.e. whether the currently processed item is the last in the list. Here the code in the commented section is run only when the last list item in $MyList is being processed:

	$MyList.each(anItem){
		if(anItem==$MyList.last){
			// some code here ...
		};
	};

Note that '$MyList.last' is not a test in itself. Rather, it supplies the value of the last list item which can be tested against the currently processed item.
