Not removing unused import if has same name function

[abhimanyu003]

PHP CS Fixer not removing unused import that has the same name as that of the function used somewhere in class.

Sample Code

<?php

namespace App\Controllers;

use App\Api\Controller;
use Zend\Diactoros\Exception;

class ValidationController extends Controller
{
    public function ipSubnet()
    {
        return exception('Something', 404);
    }
}

Expected Code

<?php

namespace App\Controllers;

use App\Api\Controller;
// Remove unused import here

class ValidationController extends Controller
{
    public function ipSubnet()
    {
        return exception('Something', 404);
    }
}

Hi. Thanks you for your report 👍
It looks like sth we could improve for sure, happily it's not causing issues for changed code.
Sadly, maintainers here cannot handle all filed issues themselves.
Could you help with it and propose a solution (probably for 2.2 branch) ?

it is and it isn't related I think, function imports and class imports are done explicitly so could be checked against, with or without checking comments and/or PHPDocs.
