Re: Arrow function expressions in PHP

When you choose the function($x) ~> $x * 2 (or with ==> or =>

operator), you end up saving around 5 or 6 characters from the "long declaration", ending up with "not-so-short closures" instead. You save a little bit more if you have the implicit "use", but that's one thing people are torn about, by looking at the discussion about the RFC, but I think it's too long, for "short closures". 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. Regards, -- Rowan Collins [IMSoP]
