<pre>using Map = std::map<int, std::vector<std::string>>;
void wrong1(const Map& m)
{
for (const std::pair<int, std::vector<std::string>>& p : m)
{}
}
void wrong2(const Map& m)
{
std::for_each(m.begin(), m.end(), [](const std::pair<int,
std::vector<std::string>> p){
});
}
The warning catches the first case but not the second:

If that analysis is not too expensive it could also warn about iteration done
by various algorithms.</pre>
