Change to Too Few Args Exception RFC

Hey all, I know this is a little late in the process, but it's something I've noticed while prepping some content around 7.1. This RFC: https://wiki.php.net/rfc/too_few_args Passed, and has been implemented, but I feel that throwing an \Error exception is a mistake. I think we should another more concrete exception class for this error: \TooFewArgumentsError extends \Error A use case where this may trivially occur is where you are using argument unpacking and the unpacked array is too small. Writing this, just looks bad: try { foo(… $args); } catch (\Error $e) { } compared: try { foo(… $args); } catch (\TooFewArgumentsError $e) { } Thoughts? Dmitry? Given the tiny change this is, and that is backwards compatible with the original RFC, I would like to add this to 7.1 for beta3. I think I can make this change myself. - Davey
