Closure numbering is not working correctly

[flip111]

php

<?php
namespace MySpace;

class TestClass {
    public function __construct() {
        $foo = function() {};
    }
}

output files:

testclass.zep

namespace MySpace;

class TestClass
{
    public function __construct() -> void
    {
        var foo;

        let foo =  new TestClass__constructClosureOne();
    }

}

testclass__constructclosurezero.zep

namespace MySpace;

class TestClass__constructClosureZero
{

    public function __construct()
    {

    }

    public function __invoke()
    {
    }
}

notice trying to instantiate class TestClass__constructClosureOne but class is TestClass__constructClosureZero --> One or Zero ??
