Subject: using lambda in class_eval

Hi All,

I'm looking to do something like:

  def test(name, proc)
    class_eval(<<-EOS, __FILE__, __LINE__)
      def #{name}_string=(str)
        # do stuff, whatever
        self.#{name} = proc.call(str)
      end
    EOS
  end

and I want to call it like e.g.:

  class Project
    attr_accessor :due_at
    test :due_at, lamdba { |x| Time.parse(x) }
  end

and then:

  Project.new.due_at_string = "2008-01-01 00:00"
  puts Project.new.due_at   # should result in a Time object


The problem I'm facing is: how can I call proc from within the
interpolated string that is given to class_eval ??  How should I write
my class_eval differently?



Best regards,
Jimmy
