It's a bit hard to do those things in PHP. It is possible to use the
memory address belonging to the variable for this, but that could be
slow. It's possibly also dangerous because I'd have no idea whether the
variable was already freed from memory as well :/ It might be possible
in some other way, but I can't quite think of how to implemented it.
