This is an interesting idea, though I don't think I have encountered the 
problems with which you motivate PropertyGuard.

For use in a library, though, I fear the string-based mechanism is too 
inefficient. For use within QtWidgets, say, I'd suggest a mechanism that works 
on the member data directly.

Thanks,
Marc
