Maybe we should start printing ASCII in future in some of the error paths... I work on image processing; when we get an image we don't recognize, we print out the first few bytes in hex & ascii. Often, it's an error message or HTML error page. The user's code takes the results of an HTTP fetch and sends it to us, forgetting to check for errors.
