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: point.rb
    path of file: ./repos/truffleruby/bench/chunky_png/chunky_png/lib/chunky_png
    
    the code of the file until where you have to start completion: module ChunkyPNG
  
  # 
    
  def self.Point(*args)
    case args.length
      when 2; ChunkyPNG::Point.new(*args)
      when 1; case source = args.first
          when ChunkyPNG::Point; source
          when ChunkyPNG::Dimension; ChunkyPNG::Point.new(source.width, source.height)
          when Array; ChunkyPNG::Point.new(source[0], source[1])
          when Hash; ChunkyPNG::Point.new(source[:x] || source['x'], source[:y] || source['y'])
          when ChunkyPNG::Point::POINT_REGEXP; ChunkyPNG::Point.new($1.to_i, $2.to_i)
          else 
            if source.respond_to?(:x) && source.respond_to?(:y)
              ChunkyPNG::Point.new(source.x, source.y)
            else
              raise ArgumentError, "Don't know how to construct a point from #{source.inspect}!"
            end
