It could, but I think it just happens too rare that someone
wants to do this. In more than 2 decades of programming, I
had this need only two or three times, for example.

> newfile = File.new("test1","w")
> newfile.puts "This line should appear at the top of each file";
> 
> oldfile = File.open("test", "r+")
> oldfile.each_line { |line| newfile.puts line}
> oldfile.close();

or simply

  newfile.puts(File.read("test"))

so you don't need the Ruby variable 'oldfile'.

> newfile.close();
> 
> File.delete("test");
> File.rename("test1", "test");
