Hi Lester, I am not blocking anything. My objective is to provide union types. Using union types, you will declare your return type as 'int|bool'. That's why I was pushing to integrate this feature in the first release. It will be done if we have enough time, but it is a lot to integrate in a discussion that must be quite short, as time is restricted. I am surely not thinking all possibilities :) but returning integer or false is usual and in scope. The solution is not to authorize (bool -> int) conversion (as it would have to support (bool -> anything)), but support 'int|bool', 'resource|bool', and similar syntax. So, the solution is completely different from the (int -> bool) question. Even, if we don't release union types in 7.0, it will be clearly stated that it is a required follow-up. That's not perfect but we do it as fast as we can and everyone is welcome to help. What does this mean in your case ? Just that, as long as the feature is not available, your function won't have an explicit return type. Period. And, please, don't change false to 0 ;). Regards François
