Sorry, I didn't notice you were doing that.

But this doesn't seem useful to me. What if you
have two instances of Tricky in use at the same
time? They're going to interfere with each other.

I suppose you could make it work if you created
a new class each time. But my earlier comment
stands -- I don't want to preclude optimizing the
common case for the sake of an uncommon case.
