And if you want to detect a failure to read a boolean (rather than
simply EOF) follow the loop with:
       if (!iss.eof())
           cout << "fail" << endl;

That should give the same behaviour with 4.1 and 4.4 for your test,
and for the case where the stream fails because it contains a
non-boolean value such as "true true x" or "true true fal"

Testing !iss.eof() tells you that the loop exited for some reason
other than reaching EOF, i.e. it couldn't convert the input to bool.
