Today, I want to announce my second RFC to php 8.7
https://wiki.php.net/rfc/array_shorthand
This RFC brings a IMO useful syntactic sugar to array's
construction and destruction. I hope you'all find this
interesting! To be short:
```
$point = [:$x, :$y, :$z]; // ['x' -> $x, 'y' -> $y, 'z' -> $z]
[:$x, :$y, :$z] = $point; // reverse.
```
I am not convinced by the premise of this RFC: it opens with the claim
that associative arrays often repeat a key and a variable with the same
name, but it offers no evidence for this, and it does not match my experience.
A syntax change should be backed by data, for instance an analysis of a
representative body of real-world code.
Even if the pattern were common, I do not see any benefit in the proposed
syntax. It saves a few characters but adds another form that every reader
and every tool has to understand.
I am sorry, but I will vote against this RFC.
