SproutCore: Monkey-patched SC.Record to get SC.Record.attr keys as an Array via class method

sc_recordattributes.js

SC.Record.mixin({
  recordAttributes: function() {
    var obj = this.prototype;
    var ret = [];
    for(var key in obj) {
      if ( SC.kindOf(obj[key], SC.RecordAttribute) )
        ret.push(key);
    }
    return ret;
  }
});

MyApp.MySCRecordSubclass = SC.Record.extend({
  title:  SC.Record.attr(String),
  body:   SC.Record.attr(String)
});

// MyApp.MySCRecordSubclass.recordAttributes()
// => ["title", "body"]

man, it was so late in the evening when i did shit like that. updated!
