[Development] QStringLiteral vs QLatin1String , foreach vs for range

[Gunnar Roth]

Hi,
I saw quite some changes like https://codereview.qt-project.org/#/c/145961/ <https://codereview.qt-project.org/#/c/145961/>  Replace QStringLiteral with QLatin1String in QFileSelector.
I also read about the problem of QStringLiteral concerning plugins, but what is the idea behind these changes ? 

There is also a lot of replacing foreach with range for loops? What is the idea behind this? Any links to read?


Regards,
Gunnar Roth
