Ah, my bad, I was damn looking at something completely else. :-( Now I found the
relevant section (12.3.2. Conversion functions) and see that adding 'explicit'
seem to fix all the problems we are now trying to solve with safe_bool. Thanks
for setting me straight. Problem solved then... well, it is being taken care of,
anyway. Sorry for all the noise.
Thanks,
