How is that even possible? ------------------------------------------------------------------------ [2015-03-29 09:31:46] benjamin dot morel at gmail dot com Now would be the time indeed! Could a core developer comment on this issue? ------------------------------------------------------------------------ [2015-03-14 19:46:39] ianbytchek at gmail dot com Any chance to account for this in PHP 7? I've read that many things in the core are being re-written / -factored. Would now be the right time to look into this? ------------------------------------------------------------------------ [2014-09-08 09:25:28] benjamin dot morel at gmail dot com By the way, it's interesting to note that calling __toString() manually works fine: class A { public function __toString() { throw new Exception(); } } echo (new A); // fatal error echo (new A)->__toString(); // exception Still no news on that issue, 2 years later? It's a very big blocking issue for doing interesting things in modern frameworks. ------------------------------------------------------------------------ [2012-12-05 01:13:22] aharvey@php.net Suspending: as Stas explained in the linked e-mail thread, it's "pretty hard" to do in the current engine. Should there ever be a Zend Engine 3, however, this could be revisited. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
