Req #70549 [NEW]: Allow `new Foo()->bar()` without parens around `(new Foo)`

From: vovan-ve at yandex dot ru Operating system: PHP version: 7.0.0RC3 Package: Scripting Engine problem Bug Type: Feature/Change Request Bug description:Allow new Foo()->bar() without parens around (new Foo) Description: ------------ PHP 5.4 allowed us to chain member assess to new Foo, but there must be parens: (new Foo)->bar(); (new Foo(42, 37))->bar(); something((new Foo(42, 37))->lorem()->ipsum()->dolor()); Why do we need that redundant parenses? Compare what ECMAScript allows - you know: new Foo().method(); new Foo().field; new some.where.Foo().method(); new Foos[i]().method(); new (anything)().method(); PHP 7 should to remove redundant parens. Test script: --------------- class Foo { protected $id; public function __construct($id) { echo "new ", get_called_class(), "($id)\n"; $this->id = $id; } public function __toString() { return get_class($this) . "{" . $this->id . "}"; } public function bar($x) { echo $this, "->", __FUNCTION__, "($x)\n"; return $this; } public function val($x) { echo $this, "->", __FUNCTION__, "($x) => $x\n"; return $x; } public function lorem(self $foo, $x) { echo $this, "->", __FUNCTION__, "($foo, $x)\n"; $foo->bar($x); return $this; } } new Foo(10)->bar(20)->bar(30)->bar(new Foo(40)->val(50)); new Foo(60)->lorem(new Foo(70)->bar(80), new Foo(90)->val(100)); // same as // (new Foo(10))->bar(20)->bar(30)->bar((new Foo(40))->val(50)); // (new Foo(60))->lorem((new Foo(70))->bar(80), (new Foo(90))->val(100)); Expected result: ---------------- new Foo(10) Foo{10}->bar(20) Foo{10}->bar(30) new Foo(40) Foo{40}->val(50) => 50 Foo{10}->bar(50) new Foo(60) new Foo(70) Foo{70}->bar(80) new Foo(90) Foo{90}->val(100) => 100 Foo{60}->lorem(Foo{70}, 100) Foo{70}->bar(100) Actual result: -------------- Parse error: syntax error, unexpected '->' (T_OBJECT_OPERATOR) -- Edit bug report at https://bugs.php.net/bug.php?id=70549&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70549&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70549&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70549&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70549&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70549&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70549&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70549&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70549&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70549&r=support Expected behavior: https://bugs.php.net/fix.php?id=70549&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70549&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70549&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70549&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70549&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70549&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70549&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70549&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70549&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70549&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70549&r=mysqlcfg
