Yes, we discussed.
But I wasn't agree with "goto" at all.
Now after looking in the patch, I see that limited "goto" can work.
I still don't like "goto", but reusing name "break" for "goto" is mach
worst.
The following code works fine with Sara's patch:
<?php
while (1) {
break L; /* why is it named "break"? This is "goto"! */
}
if ($a) {
try {
L:
} catch (Exception $e) {
}
}
?>
BTW: some languages has "break label" operatopr but it means exit from loop
marked with specified label (this makes sense).
L: while (1) {
while (1) {
break L; /* the same as "break 2" */
}
}
Thanks. Dmitry.
