About the implementation of the deprecation notice, I agree that it should be updated to be exception-safe. About the issue if it being dealt with correctly everywhere, I'm honestly more inclined towards dealing with it when/if it becomes a problem. I think the number of users that 1) Start an array with a negative number, 2) Use implicit keys afterwards and 3) Promote Notices to Exceptions must be a very very small subset. Would you consider this an acceptable approach for this specific case? Thanks, Pedro
