I think that code like this reads better without a local RetainPtr variable:

    return adoptCF(CFURLResponseCopySuggestedFilename(cfURLResponse())).get();

In fact, I would write this:

    CFURLResponseRef underlyingResponse = cfURLResponse();
    if (!underlyingResponse)
        return String();
    return adoptCF(CFURLResponseCopySuggestedFilename(underlyingResponse)).get();

I wouldn't call it 'underlying' though as it doesn't describe the role of a synthesized CFURLResponse very well.
