 I often use an idiom:
    if (!dynBitset.test(pos)) {
       dynBitset.set(pos);
       // do a once-only operation

 It would be nice to have something like:
    if (!dynBitset.test_set(pos)) {
       // do a once-only operation

 Yes, it could be done by saving a temporary reference, but this form is
 compact and easy to understand.
