That's a nice addition and a beginning to distinguish void from null, as I imagine the function still returns null. Now, what about making void a real zval type ? It would open a lot of possibilities. Unlike null, conversions from void would raise an error. It would also be rejected as argument input type but could be used as an output type when arg is passed by ref, it could be the default type for return_value (huge BC break here) and so on... There's a need for a real 'no value' type different from null, as null has too many uses. If defined correctly, it can be a powerful addition.
