Ruby blocks to change scope to specific variable

I'm a complete newbie in ruby but I can feel that this code can be improved. 

    class LoginPage < BasePage
       def initialize(session)
         @session = session
       end

       def login(params)
         @session.within '#login-form' do
           @session.fill_in 'Login', with: params[:login]
           @session.fill_in 'Password',with: params[:password]
         end
       @session.click_button 'Login'
       end
     end

I was thinking to do something like:

@session do 
  within '#login-form' do
    fill_in 'Login', with: params[:login]
    fill_in 'Password', with params[:password]
  end
  click_buttton 'Login'
end

But this code won't work. Any idea how to change scope of these method calls to make them calls to specific instance variable.

You can do this with instance_eval.

@session.instance_eval do  
  within '#login-form' do 
    fill_in 'Login', with: params[:login] 
    fill_in 'Password', with params[:password] 
  end 
  click_buttton 'Login' 
end

However I'd argue that this makes your code confusing to read since one could easily miss the instance_eval when scanning through the code.
