Subject: Object methods

Hello there. :-)

Ok, I know I can do this to add a method (and a class)
to an object:

irb(main):001:0> s = "Testing!"
=> "Testing!"
irb(main):002:0> class <<s
irb(main):003:1>    def says
irb(main):004:2>       puts "s says:"+self
irb(main):005:2>    end
irb(main):006:1> end
=> nil
irb(main):007:0> s.says
s says:Testing!
=> nil
irb(main):008:0> x = "Another test."
=> "Another test."
irb(main):009:0> x.says
NoMethodError: undefined method `says' for "Another
test.":String
        from (irb):9
        from :0
irb(main):010:0> 

My question is, dinamically, how to do that? Just like
this:

irb(main):010:0> x.class.class_eval %q(def x.says()
puts "x says:"+self end)
=> nil
irb(main):011:0> x.says
x says:Another test.

Or there is another shorter way to do that, with an
object? To build an object method with some parameters
like a string or a Proc?

Thanks! :-)
