I assume you want to say that the linked answer explicitly explains the problem.

Should we make use of this feature when programming PHP or not?

I can only remind again that the first comment from php.net obviously misread 
this report.

I am _missing_ the fatal error.

Actually I'm concerned that

reset( (get_array()) );

does _not_ give a fatal error. This contradicts the last comment There's 
really 
no way to get around that [getting a fatal error].

Why does it not give a fatal error? There is no variable.

reset() requires a variable that can be passed by reference. There's really no 
way 
to get around that, hence the fatal error.

within = without in the description.

Description:

PHP 5.3 is giving me nice, sound FATAL ERRORS when using functions like reset() 
within a variable. However it looks like that it's not always taken care of 
that consequentially.

I don't even get a strict standards warning even.

Test script:
---
?php
error_reporting(~0);

function get_array() {
   return Array(1);
}

function foo() {
   // return reset( (get_array()?:null) );
   //   ^Fatal error: Only variables can be passed by reference
   return reset( (get_array()) ); 
  // ^Only? This one works OK
}

foo();


Expected result:

Fatat error.

Actual result:
--
All fine.
