I think the filter method could be described a little more directly, as a method that retains only those elements that pass the required criteria, rather than as a method that removes those that fail the condition.

In fact, the description in the method syntax is wrong, I think - it says the method returns a copy of the original wrapped set without the filtered elements, whereas it should be with only the filtered items.

The entire description of parameters etc would be better presented as a direct screening mechanism rather than the indirect, roundabout removal explanation that is there now.
