while i tried to improve performance of the array functions i developed a new pass type - pass as const which doesn't touch the passed variable at all and is compatible with temp vars, too. Maybe your problem here is a reason to really implement that. Andi what do you think?
I think the feature you are proposing will likely be necessary either way. It can also make the output of debug_zval_dump() reliable as implicit separation of zval instances results with bogus reference counts.

There were some good reasons not to implement this change and it definitely just complicated things without giving a real gain. Making debug_zval_dump() reliable is not a good reason. Andi
