Well, it's dependent on the ability to derive from QStringView. As I said, I 
want to explore this possibility.

There are three possible cases:

0) no derivation
Then my QString and QByteArray updates are still mostly valid and can be taken 
in for Qt 6. The one change I probably want to make is to start using size_t 
and ssize_t like QStringView does.

1) deriving, but not adding the d pointer
(so sizeof(QStringView) remains 2*sizeof(void*)
In this case, this "rebasing" of QString on top of QStringView will eliminate 
a lot of code and require a large refactoring.

3) deriving and adding the d pointer
(so sizeof(QStringView) becomes 3*sizeof(void*))
It's (1) plus more work.
