Re: [RFC] Nullable Types

Hi Thomas, Sorry for the delay. I was traveling last week. By convention return; in PHP is an early return for a function that returns nothing at all. I think it can be confusing when reading a function to look at a return; line and have to remember to look elsewhere to discover what that means. And it can mean something different in every function. I prefer to write functions that return only the declared type. In some cases I need to write functions that return only the declared type or null. That's the limit of what I think PHP 7.1 should provide. Hence, for me this has no attraction but it does introduce new ways to write bugs. So I am not enthusiastic.
