Subject: [RCR] IO#readn

Hi,

I suggest to add a method readn to the IO class (and to StringIO,
Socket...), which behaves similar to read(n), but raises an exception if
the returned string is not of size n.

  class IO
    def readn(n)
      str = read(n)
      raise if str.nil? or str.size != n
      str
    end
  end 

It's annoying to test for it in the application.

Regards,

  Michael
