want.
+ An alternative to Qt's \c foreach loop is the range-based \c for that is
+ part of C++ 11 and newer. However, keep in mind that the range-based
+ \c for might force a Qt container to \l{Implicit Sharing}{detach}, whereas
+ \c foreach would not. But using \c foreach always copies the container,
+ which is usually not cheap for STL containers. If in doubt, prefer
+ \c foreach for Qt containers, and range based \c for for STL ones.

In addition to \c foreach, Qt also provides a \c forever
pseudo-keyword for infinite loops:
