title: Is boost::lexical_cast redundant with c++11 stoi, stof and family?
body: <p>Is <code>boost::lexical_cast</code> redundant now that C++11 introduces <a href="http://en.cppreference.com/w/cpp/string/basic_string/stol"><code>stoi</code>, <code>stof</code></a> and family, or is there any reason to still use it? (apart from not having a C++11 compiler) Do they provide exactly the same functionality?</p>
