How do I use boost::lexical_cast and std::boolalpha? i.e. boost::lexical_cast< bool >(“true”)

I am trying to cast from string to bool with the method lexical_cast as I show below:

boost::lexical_cast<bool>("false");

The problems is that it throws the exception 

boost::bad_lexical_cast

I have read the documentation and I understand that boost::lexical_cast<bool>("false") is correct.

    "I understand that ... is correct"? The documentation doesn't say that. In fact there was [a discussion in the boost community](http://lists.boost.org/Archives/boost/2002/05/30074.php) some time ago about this issue, and they ended up accepting that there is no simple 'correct' way to design this. – Yakov Galka Jul 06 '12 at 08:10
