I presume that [begin, end) is an iterator sequence of Landmark instances? 
Then ??? = boost::bind(&Landmark::getName, _1), meaning that the first 
parameter to std::equal<std::string>::operator() is a call to 
Landmark::getName where the object parameter (this) is the first argument 
(_1) to the bind function object.
