why not allow user-defined conversion base class (or reference it) when base inacessible: protected or private ? when there class d , public base b , there implicit rule bind references b ( b& or b&& , possibly cv-qualified) objects of class d , user-defined conversion b& doesn't make sense. when base class protected or private , implicit rule not applicable anymore. why not allow use user-defined conversion b& (or const b& or b&& etc.)? it allowed, nothing in standard prohibits this. states such conversion operator never used. [class.conv.fct]/1 : a conversion function never used convert (possibly cv-qualified) object (possibly cv-qualified) same object type (or reference it), (possibly cv-qualified) base class of type (or reference it), or (possibly cv-qualified) void. overload resolution prefer base class constructor on conversion operator, , conversion operator never called, unnecessary implicit conversions. acces
