1. 函数参数可以任意类型的

2. 返回值是bool类型

3. 编译器没有提供默认实现，不能直接使用？

\#define COMPARE(\_op\_)                                           / inline bool operator \_op\_ (const sp& o) const \{              /     return m\_ptr \_op\_ o.m\_ptr;                                  / \}                                                               / inline bool operator \_op\_ (const wp& o) const \{              /     return m\_ptr \_op\_ o.m\_ptr;                                  / \}                                                               / inline bool operator \_op\_ (const T\* o) const \{                  /     return m\_ptr \_op\_ o;                                        / \}                                                               / template                                            / inline bool operator \_op\_ (const sp& o) const \{              /     return m\_ptr \_op\_ o.m\_ptr;                                  / \}                                                               / template                                            / inline bool operator \_op\_ (const wp& o) const \{              /     return m\_ptr \_op\_ o.m\_ptr;                                  / \}                                                               / template                                            / inline bool operator \_op\_ (const U\* o) const \{                  /     return m\_ptr \_op\_ o;                                        / \}
