Actually, after reading up on this [1] it seems that this is actually correct, since with -std=c++11 std::istream defines an explicit bool() operator that would be invoked by the static_cast. Nevertheless, returning "input_stream.good()" is equally correct in the given code snipped. Best, Gert [1] http://en.cppreference.com/w/cpp/io/basic_ios/operator_bool
