Subject: instance_eval to evaluate methods inside a block in context

http://pastie.caboo.se/114839

Can anyone tell me why this wouldn't/shouldn't/should work? I don't
want to pull out all of my hair trying to figure this out if it isn't
even possible.


Thanks,
Adam


class Calculator
  def evaluate(&script)
    self.instance_eval(&script)
  end

  def two
    "2"
  end
end

class Foo
  def hi
    puts "hi"
  end

  def howdy
    Calculator.new.evaluate do
      puts two
      hi
    end
  end
end

Foo.new.howdy
