        [ImplementsFunction("tieArrayValue")]
        public static object tieArrayValue([PhpRw] ref PhpArray arr, object key, object value)
        {

        }

        public static object tieArrayValue([PhpRw] ref PhpArray arr, object key)
        {
...
        }

    public static object tieArrayValue([In] object obj0, [In] PhpStack obj1)
    {
      switch (obj1.ArgCount)
      {
        case 2:
          PhpReference phpReference1 = obj1.PeekReferenceUnchecked(0); //why 0? it's throws exception
          PhpArray phpArray1 = phpReference1.value as PhpArray;
          // ISSUE: explicit reference operation
          // ISSUE: variable of a reference type
          PhpArray& arr1 = @phpArray1;
          object key1 = obj1.PeekValueUnchecked(2);
          obj1.RemoveFrame();

          phpReference1.value = (object) phpArray1;
          return obj2;
        case 3:

      }
    }

PeekReferenceUnchecked(0); should never work, will be fixed - THANKS!

ref causes explicit referencing the variable, maybe can be discussed?

I need to change bool to PhpArray if i got bool in first argument (original methods has object as first argument and also has this bug)
