RFC proposal for alternative list syntax

Hi!

// 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];

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.
