Subject: Scalar Type Hint
From: christian.kaps@mohiva.com (Christian Kaps)

Hi internals,

someone in the "Return Type Hinting for Methods RFC" thread had the idea 
of a "numeric" type hint. I will capture this idea and propose a 
"scalar" type hint. I understand the problem of the current discussion 
about scalar type hints(int, float, string, double, ...). But there 
should be a possibility to define a "scalar" type hint to restrict 
arguments to scalar types.

function setName(scalar $name) {}

class Foo {
     public function __toString() {}
}

setName(1) // pass
setName(true) //pass
setName('Christian') // pass
setName(new Foo) // pass
setName(array()) //fail
setName(new stdClass) //fail

Why this isn't possible?

Christian
