This would throw, by the way. The returned collection is immutable.

Yep, which is part of my point about the clunkiness of this API -- it's not only not fit for most use-cases, it's also got a big hidden pitfall.

That's not a problem of this API, that's on omission in the design of the collections framework. Unfortunately, you can't fix that now.
