In May 2010, the GCC steering committee decided to allow use of a C++ compiler to compile GCC. The compiler was intended to be written in C plus a subset of features from C++. In particular, this was decided so that GCC's developers could use the destructors and generics features of C++
从GCC的观点来看，C++最有价值的部分，是析构函数和泛型。
析构函数是最直接的资源管理方法，也是最直接的scope工具；基于析构函数可以做出很多有价值的设计。
泛型是大型编程语言的必需品；虽然泛型的使用非常复杂而且易出错，但是目前来看泛型仍然是实现容器的最佳办法。业务开发要避开泛型，但是基础类库却又需要泛型。
Bionic lacks many features found in full libc implementations, such as wide character and C++ exception handling support.
宽字节并不能解决unicode的问题，但是带来了一堆麻烦，去掉最好。C++的异常，带来的问题比它解决的问题还多，去掉最好。
