 # strict-iterators
 
 Warns when `iterator` objects are implicitly cast to `const_iterator`.
 This is mostly equivalent to passing -DQT_STRICT_ITERATORS to the compiler.
 This prevents detachments but also caches subtle bugs such as:
 
     QHash<int, int> wrong;
     if (wrong.find(1) == wrong.cend()) {
         qDebug() << "Not found";
     } else {
         qDebug() << "Found"; // find() detached the container before cend() was called, so it prints "Found"
     }
 
     QHash<int, int> right;
     if (right.constFind(1) == right.cend()) {
         qDebug() << "Not found"; // This is correct now !
     } else {
         qDebug() << "Found";
     }
