You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: base.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/lib/error_highlight
    
    the code of the file until where you have to start completion: require_relative "version"

module ErrorHighlight
  # Identify the code fragment that seems associated with a given error
  #

    
    def spot_opcall_for_name
      nd_recv, op, nd_arg = @node.children
      fetch_line(nd_recv.last_lineno)
      if nd_arg
        # binary operator
        if @snippet.match(/\G[\s)]*(#{ Regexp.quote(op) })/, nd_recv.last_column)
          @beg_column = $~.begin(1)
          @end_column = $~.end(1)
        end
