Re: [RFC] Keep type of reference params

I think I’d be positive of adding inout keyword in order to: - Check type of out is equal to type of param( like example of my first email ). - Avoid modifying caller var value when the function throws an exception

Another huge advantage of adding inout parameters is that we could make it mandatory to mark at the call-site, and get the advantages of this RFC with less of the compatibility hassle of changing the way references work: https://wiki.php.net/rfc/explicit_send_by_ref We'd still need to figure out how to smoothly transition built-in functions to use inout rather than by-ref parameters; but then we already have magic "prefer-ref" in internal functions, so maybe we could come up with some kind of "prefer-inout".
