Making stdClass iterable

Hi everybody I'd like to propose a change to stdClass so that it can satisfy the iterable parameter/return type. Firstly I acknowledge that this isn't an ideal solution, but I think it gets us to a better state than we're in today. It shouldn't be necessary, but while we have such a common function (json_decode) returning stdClass we should make it easy/unsurprising to work with. https://wiki.php.net/rfc/iterable-stdclass Thanks, Craig
