A few years ago, I built this object for use in a larger project. It sat within that project and gathered dust since then. But, it was pretty useful, so I decided to extract it into its own package. Maybe it'll only be useful to me, but who knows!

NOTE: this is not (at this time) intended to be an implementation of \SessionHandlerInterface. Instead, it's just a way to make $_SESSION feel a little more object oriented and a way to avoid messing with the superglobal within code if you don't want to.
