Subject: functions returning references to function calls
From: tater@potatoe.com (Brad Bulger)

Hello. I found in PEAR DB class something that seemed like small BC issue.
The package maintainer thought it sounded like bug. If anyone would comment?

function &foo() { return new barclass; }

gives error saying
PHP Fatal error:  Only variables or references can be returned by reference

this is correct for php 5, yes? same as

function &foo() { $a = array(1); return array_keys($a); }

which gives same error in 5, but is acceptable in 4.

Thank you.
