I see what you're doing now: unsetting the variable, not the array
element referenced by the variable. You're right, it does work.

It's not exactly better than knowing what's wrong, though... it's
different. I already had a workaround, although it was not quite as
elegant. My desire now is to find out whether the behavior I described
is due to something I don't understand about PHP, or to a bug. If it's
something I don't understand, I want to understand it. If it's a bug,
I want to report it.
