strange ast with list

[alexander-akait]

Input:

list("id" => $id1, "name" => $name1) = $data[0];

Output:

 List {
        kind: 'list',
        loc: 
         Location {
           source: null,
           start: Position { line: 29, column: 0, offset: 730 },
           end: Position { line: 29, column: 36, offset: 766 } },
        arguments: [ [ 'key', [Object], [Object] ], [ 'key', [Object], [Object] ] ] }

It is expected behavior?

Oups, it's a very old form of AST from the first 0.x version. I've missed to update it when I've done changes on nodes. It will be the same node as arrays array("id" => $id1, "name" => $name1)
