RSpec: Expect to change multiple

In RSpec 3 you can setup multiple conditions at once (so the single expectation rule is not broken). It would look sth like:

expect {
  click_button 'Save'
  @user.reload
}.to change { @user.name }.from('donald').to('gustav')
 .and change { @user.updated_at }.by(4)
 .and change { @user.great_field }.by_at_least(23}
 .and change { @user.encrypted_password }

It is not a complete solution though – as far as my research went there is no easy way to do and_not yet. I am also unsure about your last check (if it doesn’t matter, why test it?). Naturally you should be able to wrap it within your custom matcher.
