Bug description:Traits cannot be used as function/method typehints
Description:
------------
It is not possible to use trait as a typehint in function declaration.
Use case: Extending few different classes to use a trait in them where
these classes doesn't have same parent. Then I want to specify typehint,
because I require some methods which are declared by that trait.
Test script:
---------------
trait Foo
{}
class Bar {
use Foo;
}
function test(Foo $obj) {
echo 'hello';
}
test(new Bar);
Expected result:
----------------
hello
Actual result:
--------------
Catchable fatal error: Argument 1 passed to test() must be an instance of
Foo, instance of Bar given...
