It's fairly obvious this is what's happening. And normally this wouldn't 
matter as you wouldn't be able see the difference, but because of 
.tupleof this is now detectable.
I think the real question here is: while this may be what *is* 
happening, is this also what *should* happen? (i.e. "Is this a bug?")
I can't find anything specifying this behavior in the spec...
