[Seasar-user:21798] kumu.jsについで

お世話になっています。
周と申します。

kumu.js is overriding the prototype of array:

Array.prototype = Kumu.extend(Array.prototype, {
  map:Kumu.map,
  filter:Kumu.filter,
  shift:Kumu.shift,
  unshift:Kumu.unshift,
  include:Kumu.include
  
});

which is causing serious performance problems in JavaScript heavy page in IE7,8.

What's the reason? If kumu.js is trying to deal with legacy browsers without
all these methods provided, at least it should the existence of the methods
before overriding them.

Any advice or suggestion will be greatly appreciated.

Best Regards,
