Bug ID: 46565
Summary: -Wrange-loop-analysis for algorithms
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs

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.
