mention foreach (...)

\o Using Qt's foreach is ok in non-time critical code when using a QTL
container. It is a nice way to keep line noise down and to give the
loop variable a proper name:
foreach (QWidget *widget, container)
Container::iterator end = container.end();
for (Container::iterator it = container.begin(); it != end; ++it)
If the loop variable can be made const, do so. This can prevent
unnecessary detaching of shared data in some cases. So:
foreach (const QString &name, someListOfNames)
- NOT -
foreach (QString name, someListOfNames)
