class RuboCop::AST::ForwardArgsNode

A node extension for ‘forward-args` nodes. This will be used in place of a plain node when the builder constructs the AST, making its methods available to all `forward-args` nodes within RuboCop.

Not used with modern emitters:

$ ruby-parse -e "def foo(...); end"
(def :foo
  (args
    (forward-arg)) nil)
$ ruby-parse --legacy -e "->(foo) { bar }"
(def :foo
  (forward-args) nil)

Note the extra ‘s’ with legacy form.

The main RuboCop runs in legacy mode; this node is only used if user ‘AST::Builder.modernize` or `AST::Builder.emit_lambda=true`
