Re: [RFC] Void Return Type (v0.2, reöp ening)

But why "invent" (as far as PHP is concerned) this new keyword of "void" to mean exactly the same thing "null" already means - absence of a definite value?

They don't mean exactly the same thing. null is a value to represent a lack of a value. But there's also the concept of *no value at all* (a missing variable, say). The closest we have to that in PHP already would actually be unset, but that's a strange choice given it's not what we use in documentation (function prototypes, PHP manual, PHPDoc, etc. use void), and it's tainted by the bizarro (unset) cast which casts to null.
