// how to pass arbitrary "this" object for eval'ed script?

var obj = { foo: 44 };

// the following won't work. eval.apply is indirect eval call
// and so 'this' will be global object always! So, this

eval.apply(obj, [ " print(this.foo)" ]);

obj.myEval = eval;

// still won't work - still indirect 'eval' call!
