Description Ms2ger 2013-12-19 14:25:21 UTC 
With ArrayClass,

  var x = document.querySelectorAll("*");
  var y = x.concat();

leads to y ≡ [x]. It seems like ES6 @@isConcatSpreadable can fix that.
Comment 1 Jonas Sicking (Not reading bugmail) 2013-12-19 19:10:43 UTC 
Let's just do what's proposed in bug 23682 and get rid of ArrayClass
Comment 2 Domenic Denicola 2016-10-22 16:44:04 UTC 
Since it seems like ArrayClass is legacy, let's not do this.
