File.class_eval do
   def self.addmod(flags, filename)
     themode=stat(filename).mode | flags
     chmod(themode, filename)
   end
end

Although there's no error checking and the return value could probably  
be something better (like themode).

So after defining that, your 'u+r' would be:
   File.addmod(0200, 'filename')
