    return foo, bar, baz
           ^^^^^^^^^^^^^

### Attributes

arguments[R]

The list of arguments, if present. These can be any [non-void expressions](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

    foo(bar, baz)
        ^^^^^^^^

### Public Class Methods

new(source, node_id, location, flags, arguments) click to toggle source

Initialize a new `ArgumentsNode` node.

    # File prism/node.rb, line 764
    def initialize(source, node_id, location, flags, arguments)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @arguments = arguments
    end

type() click to toggle source

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

    # File prism/node.rb, line 847
    def self.type
      :arguments_node
    end

### Public Instance Methods

===(other) click to toggle source

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

    # File prism/node.rb, line 853
    def ===(other)
      other.is_a?(ArgumentsNode) &&
        (flags === other.flags) &&
        (arguments.length == other.arguments.length) &&
        arguments.zip(other.arguments).all? { |left, right| left === right }
    end

def copy: (?node_id: Integer, ?location: `Location`, ?flags: Integer, ?arguments: Array) -> `ArgumentsNode`

    # File prism/node.rb, line 793
    def copy(node_id: self.node_id, location: self.location, flags: self.flags, arguments: self.arguments)
