Well, this sounds like a reason for creating SplSet class
There's already SplObjectStorage which CAN act like a Set for objects
only. It's a terrible solution in my opinion and am working on
creating a proper one. I don't know if that effort will be accepted,
but I wanted to point out that a set already exists in the SPL.
SplObjectStorage would indeed cover one given example:

SplObjectStorage even has a detach() method for removing an element by
value, as well as implementing the various array access interfaces.
