Chris@14: Compatibility notes
Chris@14: ===================
Chris@14: 
Chris@14: To write portable code between PHP5 and PHP7, some care must be taken:
Chris@14: - `\*Error` exceptions must be caught before `\Exception`;
Chris@14: - after calling `error_clear_last()`, the result of `$e = error_get_last()` must be
Chris@14:   verified using `isset($e['message'][0])` instead of `null !== $e`.
