[20:11:12] <Krinkle>	 duesen: I think "normal" and "pass USER_ERROR" are contrary points. I believe trigger error is mainly used to create logged notices and warnings in  an easy and standalone manner. If something should exit the process there is exit; or one can throw an exception normally and let it bubble/fatal accordingly.
[20:13:12] <Krinkle>	 We very rarely use it to terminate the process, afaik it's mostly done by mistake/misunderstanding (including me once, not realising that severity error behaves different than warning, beyond merely message prefix in logstash), or in cases where an exception isn't allowed such as in __toString() during shutdown etc and you still want to short circuit with logging 
[20:13:17] <Krinkle>	 But that's pretty rare
[20:14:00] <Krinkle>	 If I recall correctly I created a task asking for a sniff against such (usually) accidental use of trigger error with that constant
[20:14:17] <Krinkle>	 Curious what you'd think about that :)
[20:20:36] <duesen>	 I agree that trigger_error with E_USER_ERROR seems pretty useless. Throwing an exception makes more sense. I think it only exists because PHP didn't use to have exceptions.
