```cpp
#include <iostream>
#include <string>
#include <string_view>
std::string_view foo(std::string_view in);
std::string_view foo(std::string_view in [[clang::lifetimebound]]) {
return in;
}
```
This leads to callers not seeing the `lifetimebound`, specially when the declaration is in header and definition is in an implementation file.
The policy should be: `lifetimebound` **must** be placed on a declaration and **maybe** placed on a definition.
