字符串 字符串现在支持 u、u8、u32 这种处理 unicode 的前缀了,然后还支持 raw string,这是从 python 学来的么,这样写 regex 终于不用抓狂了… 另外这里的 delimiter 是 r”xxx( 和 )xxx” 了,其中 xxx 可以自己指定。这些 g++ 4.6 均支持。 user-defiend literal 不知道有啥重要作用(参考这里),似乎可以...
我们知道这里面有一些额外的代价,比如 pImpl 还有额外的 virtual function call。我们这里介绍两个技巧,用于优化 type erasure 的性能。参看这个 cppcon talk SBO 小型缓存优化 所谓的 SBO(small buffer optimization)本质上是为了避免额外的(堆)内存分配做的优化,这不仅仅对 type erasure 有效,像 string 之类的都可以...

This is by virtue of the fact that it's what your transformation function returned, and it thus transformed the return type also, and put it back into a box (because that's what map does). It's still in aBox<T>but is a box of astringnow instead of a box of numbers... Map...
