Add base class destruction to clear() in object.d 是什么意思？
我怎么没找到 clear() 这个类析构函数？ 它是可继承的吗？还是 ~this() 的函数版？ |

我怎么没找到 clear() 这个类析构函数？ 它是可继承的吗？还是 ~this() 的函数版？ 你那个数据结构如何了，好久没听你介绍了 目前跟dcollections（http://www.dsource.org/projects/dcollections/wiki）比如何，性能，内容（多少），稳定（bug）。。。 |

内容上好像差不多，你好像还多点，不知道其他怎么样，有中文文档和中文备注是个好东西。。。只是缺点 sample
2.0的新版本都支持吗？ |
