NAK to inheriting from QStringView, publicly or privately. NAK to adding 
another pointer.

If you need a base class for your Q6String, use QStringRef. It's already got 
what you want: tight coupling with QString. QStringView will not be that base 
class. QStringView will model whatever std::string_view models. Anything that 
pessimises QStringView as a wrapper around a char16_t literal is not 

I understand that you sit on a pile of finished changes to QString just 
waiting for Qt 6 to come around. And I welcome it (I think, we'll see when you 
upload some of it to Gerrit). But leave QStringView out of it.
