RFC proposal for alternative list syntax

Hi   I have a proposal for new alternative syntax for list   // In the old days we did this   list ($a, $b) = array (1, 2);   // With the new array syntax this has been improved to   list ($a, $b) = [1, 2];   // I think this new syntax should logically extend to   [$a, $b] = [1, 2];   Regards   Julian   Julian Rhind

list() and array() are two different language constructs, using the same syntax for them is a bad idea.

What he wrote looks very perl-ish, but with [] instead of (). The perl ideom to swap the values of 2 variables: ($b, $a) = ($a, $b); could be written in PHP as: [$b, $a] = [$a, $b]; Looked at that way (left hand of '=' only) it is not that bad.

To me it looks pretty much like pattern matching and I would like to see pattern matching in PHP. Maybe we need to add a little bit more syntax to distinguish it from normal array usage but I like the idea.

I tend to agree here but it exists elsewhere and is quite handy. Also the behavior of this expression, in this case, is obvious. Cheers,

This could be very nice shortcut to have. Seems intuitive enough; I doubt there'd be any serious confusion over this. You should draft an RFC for this, OP. --Kris

hi Julian, I've just granted you rfc wiki karma, so you should be able to create/edit pages under the rfc namespace in the wiki.

It looks like, destructuring assignment, in ES6 https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment I like! )
