# Considering Correctness

## Avoid Typeless Interfaces
|
|
|
|
|
|
Bad Idea:
|
|
|
|
```cpp
|
|
std::string find_file(const std::string &base, const std::string &pattern);
|
|
```
|
|
|
|
Better Idea:
|
|
|
|
```cpp
|
|
std::filesystem::path find_file(const std::filesystem::path &base, const std::regex &pattern);
|
|
```
|
|
|
|
The above is better but still suffers from having implicit conversions from `std::string` to `std::filesystem::path` and back.
|
|
|
|
Consider using a typesafe library like

|
|
|
|
Note that stronger typing can also allow for more compiler optimizations.
