  # `Astrolabe::Builder` is an AST builder that is utilized to let `Parser` generate AST with

  #
  # @example
  #   require 'astrolabe/builder'
  #   require 'parser/current'
  #
  #   buffer = Parser::Source::Buffer.new('(string)')
  #   buffer.source = 'puts :foo'

  #   builder = Astrolabe::Builder.new
  #   parser = Parser::CurrentRuby.new(builder)
  #   root_node = parser.parse(buffer)

    #
    # @return [Node] the generated node
