Revision 16 of this benchmark created on

Setup

function f() {
        return this;
    }
    var that = {
        f: f
    };
    var bind = function(f, ctx) {
      return function() {
        return f.apply(ctx, arguments);
      };
    };
    var rawBound = bind(f, that);
    var bound = f.bind(that);
    var that2 = Object.create(that);
    var that3 = {};
    var that4 = Object.create(that3);
