Req #75576 [NEW]: C++-like function-try-blocks

From: enclaved at safe-mail dot net Operating system: All PHP version: 7.2Git-2017-11-27 (Git) Package: PHP Language Specification Bug Type: Feature/Change Request Bug description:C++-like function-try-blocks Description: ------------ I am proposing a patch to bring C++-like function-try-block shorthand syntax for whole-function try-catch-finally blocks: function fuu($foo, $bar): void try { may_throw($foo); may_throw($bar); } catch (FuuException $e) { echo $e->getMessage(); } The proposed patch is attached. It makes purely cosmetic modifications to zend_language_parser.y grammar to augment plain functions, class methods, and closures to accept try-catch-finally blocks as their bodies in addition to regular compound statements. It amounts to just a handful of lines and entails no API changes. Test script: --------------- function coyote(bool $acme): void try { echo "Coyote"; if ($acme) { throw new RuntimeException; } } catch (RuntimeException $e) { /* * Coyote succeeds. */ } finally { if (empty($e)) { echo " never"; } echo " catches Roadrunner", PHP_EOL; } coyote(false); coyote(true); -- Edit bug report at https://bugs.php.net/bug.php?id=75576&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75576&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75576&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75576&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75576&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75576&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75576&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75576&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75576&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75576&r=support Expected behavior: https://bugs.php.net/fix.php?id=75576&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75576&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75576&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75576&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75576&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75576&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75576&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75576&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75576&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75576&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75576&r=mysqlcfg
