Thinking about it, it is probably a poor decision to
put the tag bits into the Value*. This incurs unnecessary
overhead as the Use::Val member is accessed frequently.

My final proposal will say that the Prev member will be used
to carry the tag bits necessary for recovering the User*.
This member is far less frequently accessed and syntactically
better isolated.
