Too much std and boost...
Как думаете, что делает этот код?

int line = 3;
ifstream f("somefile.txt");
string s;
while_loop(_3 != EOF, switch_statement(
 _3 = bind
  (&ifstream::get, _1),
 case_statement<(ifstream::char_type)EOF>(),
 case_statement<'\n'>(if_then(++_2 > line,
  _3 = EOF)),
 default_statement(if_then(_2 == line,
  bind(&string::push_back, &s, _3)))
 )) (f, *auto_ptr(new int(1)).get(),
  *auto_ptr(
   new ifstream::char_type(0)).get());
cout << s << endl;
