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.
Tom
