The new parameter "also_throwables" defaults to false, so the same
behaviour as before is preserved. If you want it to catch also the new PHP7
Error exceptions, you can just set it to true.
This is an interesting idea, but other than the specific transition to
PHP 7, I'm not sure when it would be used.
Put it this way: if Errors existed when you first wrote this code, would
you want to handle them using your custom handler functions, or would
you prefer them to the fall through to the default server White Screen
of Doom? My guess is that you'd want to pass them to the handler, even
if it immediately checked "if ($e instanceOf Error)" and used a
different output style.
Since set_exception_handler() is intended as a last-ditch "something's
gone very wrong" function anyway, I think it receiving all Throwables
makes sense, even if the BC break in your scenario is unfortunate.
