As a person reading docs only if something is not working as expected, I'm 
pondering, if there is a way to document the lifetime without documentation. 
It seems that QStringView shares problems of raw pointers and raw pointers 
issue was mostly solved by different smart pointers. So why not returning one 
of these:


Some of these could be enforced by asserts, some could be just for documenting 
the issue. Anyway, just an idea :-)
