[PHP-BUG] Bug #72159 [NEW]: Imported Class Overrides Local Class Name

From:             rod at owsy dot com
Operating system: All
PHP version:      7.0.6
Package:          PHP Language Specification
Bug Type:         Bug
Bug description:Imported Class Overrides Local Class Name

Description:
------------
When importing a class into a namespace it seems to override any classes
with that name in the current namespace (PHP 7.0+)

https://3v4l.org/tGv74

Test script:
---------------
<?php

namespace Foo {

    class Bar
    {
        public $from = 'foo';
    }
}

namespace Bazzle {
    use Foo\Bar;

    class Bar
    {
        public $from = 'bazzle';
    }

    echo (new Bar())->from;
}

Expected result:
----------------
Fatal error: Cannot declare class Bazzle\Bar because the name is already
in use

Actual result:
--------------
'foo' is echo'd
