New Comment:
The current behaviour is correct. Traits are outside the inheritance system: the
parent class is effectively defined by the composition of its own
methods/properties and any traits it uses, so trait usage is not actually
inherited. Furthermore, it doesn't really make sense to reflect trait usage down
the class hierarchy because the same trait may be used more than once within a
class hierarchy.

Description:
------------
---
From manual page: http://www.php.net/reflectionclass.gettraits#refsect1-reflectionclass.gettraits-returnvalues
---
ReflectionClass::getTraits() does not return traits inherited from ancestor classes.
Test script:
---------------
trait Balding {
public function loseHair(){
echo get_class($this) . " is losing his hair!\n\n";
}
}
class Father {
use Balding;
}
class Son extends Father {}
$Son = new Son;
$Son->loseHair();
$Reflect = new ReflectionClass($Son);
print_r($Reflect->getTraits());
Expected result:
----------------
Son is losing his hair!
Array
(
[Balding] => ReflectionClass Object
(
[name] => Balding
)
)
Actual result:
--------------
Son is losing his hair!
Array
(
)
