Wez, that patch allows for the possibility of a future 'goto' (which it calls 'jump'). It just doesn't implement it...

I think not many people use it because it's difficult to use.
Having real labels might change that.
Personally, I'd prefer real goto, as I've stated in the past.
Just for the record again, I'm +1 for goto, and +0.5 for labelled
breaks only if we've totally given up on goto.

It's just something which to begin with isn't used that much.
Grep'ed phpweb/ for it and found 0 occurrences of break n; and I
believe the people developing it would be the ones who would know how
to use it.

wholly in support of this patch.
I doubt I'm the only PHP user with that issue, due to the 'ease of
use' that allows people with no history of computer science to write
useful scripts (for which, thank you all). But I wouldn't expect a
great deal of sympathy on that point from CS graduates.
nb I think implementing goto/equivalent itself is a fairly bad idea
- I appear to be in the minority on that issue. But I don't see any
problem with introducing labels, I just see it as a more
user-friendly way of allowing nested breaks.
Am I very wrong?

I think that in 1997 when break/continue n where implemented it
would have been a nice idea, but at this stage except for being
more elegant than break/continue n it doesn't truly add anything
substantial to PHP (and as you already mentioned it's orthogonal to
the goto discussion). I think having more than 1 way of doing the
same thing, in this case, might just end up confusing people
developing with PHP (i.e. the Perl way :)
Just for the record I am coming at this from an open mind. Dmitry
did spend time on this patch, etc...
I'd recommend to bed it once and for all.

Guys and guyess,
Sara and Dmitry's patch to introduce labelled breaks was discussed
on internals@ ever-so-briefly at the beginning of December, but
there was never any decision made over it.
Given that practically everyone who survived the preceding GOTO
discussion seemed to think it was a good idea at the time, could
you please re-visit it, evaluate it, discuss it (as opposed to
talking about GOTO, which is unrelated) and either OK it or put it
to bed for once and for all?

And if it's worth anything, +1 from me.
