If there is a use for goto, that can cause certain tasks to be
acomplished faster using goto, and that implementing goto in the ZE
isn't too much work, then I don't see a problem with implementing it.
I'm not totally sure why, but Zend used goto, in the Zend Engine(one
used for php4) code for looping through opcodes. I'm sure zend saw
some benefit in using goto's when they decided to use them in the ZE
Backend.
Goto has (I believe) been described as a method of shooting yourself
in both feet at the same time. Maybe if there was an
enable_expert_mode() command to enable expert mode for that page, or
maybe a <?php_expert opening brace, that enable functionalty that is
recommended for use only by experts. - Just a thought.
