Is it possible to define a Ruby singleton method using a block?

Question

So, I want to define a singleton method for an object, but I want to do it using a closure.

For example,

def define_say(obj, msg)
  def obj.say
    p         


        

Answer 1

Object#define_singleton_method was added to ruby-1.9.2 by the way:

def define_say(obj, msg)
  obj.define_singleton_method(:say) do
    puts msg
  end
end
