They will actually work together.  If you do what I said, then you can also
pass in a specific set as Lloyd suggests...  there's just no need to unless
you want to use a specific set instead of having a empty default set
created.

I simply misinterpreted the following documentation:

Yes, it just means you can't pop() items from a set, not that you can't,
say, .remove() them.
