delete this;如果删除语句是将在该类的实例上执行的最后一条语句，是否允许？当然，我确定由this-pointer
表示的对象是newly-created 的。

我正在考虑这样的事情：

void SomeModule::doStuff()
{
    // in the controller, "this" object of SomeModule is the "current module"
    // now, if I want to switch over to a new Module, eg:

    controller->setWorkingModule(new OtherModule());

    // since the new "OtherModule" object will take the lead, 
    // I want to get rid of this "SomeModule" object:

    delete this;
}

我可以这样做吗？
