A modern programming language that makes developers happier.

kotlinlang

```
                logger.error("invalid statusCode {} from {}", response.statusCode, url.encoded)
                logger.error("connection url: ${request.url}")
                logger.error("cUrl: ${request.cUrlString()}")
                logger.error("response: $response")
                logger.error("error: {}", result.error.toString())
                logger.error(result.error.exception) { "Download Failed" }
```

gives me this output:
