```cpp
#include <set>
#include <string>
void f()
{
std::set<std::string> s;
for (const auto &str : s) {
const std::string::size_type p = str.find("(");
}
}
```
The following is only reported when using libc++:
```
<source>:9:51: warning: 'find' called with a string literal consisting of a single character; consider using the more effective overload accepting a character [performance-faster-string-find]
9 | const std::string::size_type p = str.find("(");
| ^~~
