Bug description:interface + use trait yields error for the abstract class?
Description:
------------
The code in the test script contains one trait and an interface, that uses
this
trait ("use TestTrait"). What I was trying to do here is to see how PHP
behaves if
i include "use" statement inside interface definition.
Suprisingly, test script produces very interesting result - I get a fatal
error
with the following text: "Class TestInterface contains 1 abstract method
and must
therefore be declared abstract or implement the remaining methods
(TestInterface::b)". It looks like PHP's compiler messes up when I mix
interfaces
together with "use" statement and somehow treats "TestInterface" as an
abstract
class.
I didn't go deeper to look into the problem as it's pretty clear that
something is
wrong here. In my opinion, PHP should not allow usage of "use" statment
inside
interface defitions.
Test script:
---------------
trait TestTrait {
}
interface TestInterface {
use TestTrait;
public function b();
}
Expected result:
----------------
PHP Fatal error: use of "use" statement in interfaces is not allowed.
Actual result:
--------------
PHP Fatal error: Class TestInterface contains 1 abstract method and must
therefore
be declared abstract or implement the remaining methods (TestInterface::b).
