Example: foreach ($coords as list($x, $y)) { ... }
This change slightly breaks backwards compatability, as it changes the
node structure for the previously existing `list(...) = $foo` assignments.
Those no longer have a dedicated `AssignList` node; instead they are
parsed as a normal `Assign` node with a `List` as `var`. Similarly the
use in `foreach` will generate a `List` for `valueVar`.
