Represents an array literal. This can be a regular array using brackets or a special array using % like %w or %i.
[1, 2, 3] ^^^^^^^^^
Represent the list of zero or more [non-void expressions](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression) within the array.

end
Initialize a new ArrayNode node.

Return a symbol representation of this node type. See ‘Node::type`.

def ===(other)
other.is_a?(ArrayNode) &&
(flags === other.flags) &&
(elements.length == other.elements.length) &&
elements.zip(other.elements).all? { |left, right| left === right } &&

(closing_loc.nil? == other.closing_loc.nil?)
end
Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
