This allows you to combine exception generating code with retry code to trace the execution over the retry cycle. Example:

$retry = new \Haldayne\Fox\Retry(
     $capture = new \Haldayne\Fox\CaptureErrors(
         new \Haldayne\Fox\ExceptionToError(
             function () { throw new \Exception('Oops!', rand(1,10)); }
         )
     )
);
$result = $retry();
if (false === $result) {
    die(
        $capture->
        getCapturedErrors()->
        pluck('message')->
        into(new MapOfStrings)->
        join(PHP_EOL)
    );
}
