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.

[PHP-DEV] RFC proposal for alternative list syntax

[Julian Rhind]

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

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.

[S.A.N]

It looks like, destructuring assignment, in ES6

I like! )

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

It looks nice. I like it

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.
