Greetings, Internalians.
The vote for auto-capture closures is now open. It will run until 15 July.
https://wiki.php.net/rfc/auto-capture-closure
I have voted No, because although I am more-or-less convinced that
auto-capture is a useful feature, I don't think this is the right syntax
for it.
- Having "fn" and "function" mean almost the same thing, but with such
an important difference, feels like a WTF waiting to happen.
- The RFC seems to take for granted that shorter syntax is better,
calling explicit syntax "noise"; but in that case PHP contains a lot of
"noise", and I'm not convinced that removing it would be a good thing.
- This emphasis also implies that auto-capture is a near-universal
improvement over explicit capture, rather than an alternative on equal
footing: it is the version that deserves the very best syntax possible.
I remain unconvinced by this.
- Unlike other languages, PHP normally relies on opting into scope
imports (global, $this->, etc), so lacks a mechanism to opt out and
declare a variable as local (var, let, etc). The proposed syntax offers
neither opt-in nor opt-out, relying on the implementation to do the
right thing automatically ... most of the time.
To re-iterate, I am not opposed to the feature in principle, but would
have loved to see a more open exploration of different syntax options.
