It's java code, but it shows how goto can help you get rid of nesting hell. Hi Derick, The code in that example looks more like an argument for try ... finally to me than an argument for goto. I have yet to see a good case for goto (not break) that doesn't involve parsing or error handling, and we have exceptions already for error handling flow control. But, we don't have try ... finally (and java doesn't have goto). Best Regards, Jeff -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] The jump operator
Link: http://news.php.net/php.internals/36536 One question - are you crazy? I heared about break with goto capabilities - that's understandable - you could break 2 or 3 level loops, but this one shit.

Re: [PHP-DEV] The jump operator
Well, why even add such functionality if it's doubtful it will be used. It just ads confusion and anger to users, who knows what it does and what harm can be done. GOTO functionality wasn't present in PHP and i think should never be ever. break is fine.. 2008/4/4, Alexey Zakhlestin [EMAIL PROTECTED]: On Fri, Apr 4, 2008 at 1:17 PM, Arvids Godjuks [EMAIL PROTECTED] wrote: just emotions, sorry.
