I'd probably reuse this anyway, given the number of data strcutures I've got flying around right now. Nipsu, that was kind of the point I was trying to make - I was annoyed initially for what appeared to be inconsistancies in the API's between HashSet and HashMap, and then realised I was fundamentally misusing a Set.

It doesn't make any sense to return 'previous' value from set since if there was a 'previous' value it's 'logically' the same object that you are trying to insert.
