Subject: question about instance_eval, dynamic methods and blocks

Not sure if I am attacking this correctly or not, so if anyone has any
insight, please assist.

Let me setup my situation

class Task

  attr_reader :name

  def initialize(name, &block)
    @name = name

    instance_eval <<-EOL
      def run(&block)
        yield if block_given?
        # i need the block passed to initialize to go here
        # but i am not sure how do do it
      end
    end
  end
end

t = Task.new('do_something') { puts "I want this block to be the guts of
'run' method in t instance" }

t.run { "running #{@name}" }


basically i want to dynamically create the run method whenever i create
an instance of a task, and the guts of the run method to be the block
passed with .new but i also want the ability to have run accept a block
as well.

any help is appreciated.
