PHP7 "use" statement with curly braces throws Notice: Uninitialized string offset: 0

[drupalista-br]

Declaring the "use" statements like below work just fine:

use App\SomeFolder\MyClass as Class1;
use App\SomeFolder\SomeSubfolder\MyClass as Class2;

Declaring them this way:

use App\SomeFolder\{
    MyClass as Class1,
    SomeSubfolder\MyClass as Class2,
};

Throws the following exception:

In ReflectionClosure.php line 779:
[ErrorException]

This is because PHP 7.2 allow a trailing comma to the group-use. Removing the trailing comma after the Class2 will give you a quick fix for this.

use App\SomeFolder\{
    MyClass as Class1,
    SomeSubfolder\MyClass as Class2
};

Fixed in v3.1.2
