As mentioned in other answers std contains many common names like list and error. Boost just highlights the issue as it is affected now. Invoking using undoes what namespaces were supposed to fix. Be careful with it. | |

I did that once and learned a lesson the hard way. Now I never use using outside of a function definition and rarely use using namespace at all.
