Nit: May use ZVAL_DEINDIRECT().

That said, this behavior is deprecated, so a complicated solution might not be necessary. Throwing until we eventually remove the feature sounds acceptable. |
I guess this makes sense; I'll see how easy it is to do |

This will implicitly advance when the current element is unset. E.g. with a current(), unset(), current(). I think it would be reasonable for current() not to advance, but to throw if the element is undef.
