These inconsistencies exist for two reasons: - Opposition to doing it the other way - Hack already doing it this way I don’t think function void foo(); will happen, since that’s been previously rejected as it breaks gripping for “function foo”. Similarly, I don’t think public $foo: Foo; will happen, given Hack does it as public Foo $foo;. PHP doesn’t need more inconsistency, sure, but we must be practical here. It is bad if PHP and Hack have the same feature with different syntax, it will cause developer confusion and further segment the communities. It is bad if we don’t get return type hinting because the “consistent” syntax would upset some people. -- Andrea Faulds http://ajf.me/
