There's nothing special about $this, and thus, it can be quite a headache
to have to implement something that does special things by just assigning
to this variable.
Let's put it this way, knowing what I know about the engine's
implementation, I have very good reasons to say that this is a side effect,
that won't be very easy to implement under other implementations,
definitely not in a performance efficient way (and I'm not talking about
degraded performance with $this assignment, but rather, all assignments,
i.e., out of the question).
It's good that this question was asked, but really, be prepared to the fact
that 'no' can also be an answer.
