Reading over the list I don't think people "are torn about" it. There
are some detractors, sure, but there seem to be more detractors about
symbol choice (~) and lack of type declarations.
On a quick glance through the list I gathered the following names
expressing disapproval of the automatic capture (apologies if I've
misrepresented anyone's opinion here, it was a very quick skim through!):
Dmitry
Rasmus
Peter Petermann
Bishop Bettini
Stas
Ferenc
Thomas Punt
Plus a couple of other people on the fence on the issue (as am I):
Marco Pivetta: "I am still conflicted..."
Arne Blankerts: "I can see the benefit ... but consider it a break of
concepts (habit?) from everywhere else in PHP."
That seems like a significant proportion of the people actively
participating in the thread to me; as mentioned elsewhere, there are
more people who've voted no than have expressed their reasons on the
list, and it's a mug's game to guess which factors influence whom. Also,
remember that the votes on RFCs are intended to confirm consensus, not
replace it - the idea is not to win over just enough people to "win", so
it's not necessarily about numbers.
That's not to say that automatic capture is an absolute blocker, but I
think "the internals community is divided on it" is a reasonable summary.
