Overview

Used for modern support only: Not as thoroughly tested as legacy equivalent

$ ruby-parse -e "->(foo) { bar }"
(block
  (lambda)
  (args
    (arg :foo))
  (send nil :bar))
$ ruby-parse --legacy -e "->(foo) { bar }"
(block
  (send nil :lambda)
  (args
    (arg :foo))
  (send nil :bar))

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