[RFC] Saner array_(sum|product)()

Hello internals, I would like to start the discussion about the Saner array_(sum|product)() RFC: https://wiki.php.net/rfc/saner-array-sum-product Currently, the array_sum() and array_product() behave differently than their userland implementation as they ignore arrays and objects, and cast the remaining types to int/float. This is in contrast with the behaviour of arithmetic operators that throw TypeErrors on types and values that are not interpretable as int/float. This RFC aims to resolve this discrepancy. Best regards, George P. Banyard
