In the above function we have used a named return paramter, which allows you to include a simple return statement without the variables you are returning. This practice can cause confusion when functions become large or the logic becomes complex, so these should be avoided.

## Use error wrapping
Bad:
```

if err != nil {
return fmt.Errorf("something bad happened: %v", err)

```
Good:
```
err = SomeAPI()
if err != nil {
return fmt.Errorf("something bad happened: %w", err)
}
```
Error wrapping allows `errors.Is` and `errors.As` usage in upper layer
functions which might be useful.
