I don't care for some few bytes and nanoseconds wasted, if not wasting 
them means "bad to read" and "bad to reuse". If my profiler tells me 
that this little extra causes a problem, then I'd be happy to go another 
route, until them I'm happy to waste some on maintainance costs that 
usually trump runtime costs my a large margin.

Kind regards,
