RSpec: Is there a not for `and change`, e.g. `and_not to change`? : <p>I find the <code>.and</code> method very useful for chaining many expectations.</p>

<pre><code>expect {
  click_button 'Update Boilerplate'
  @boilerplate_original.reload
} .to  change { @boilerplate_original.title }.to('A new boilerplate')
  .and change { @boilerplate_original.intro }.to('Some nice introduction')
</code></pre>

<p>Is there something that let's me check for <strong>no change</strong>?</p>

<pre><code>.and_not change { @boilerplate_original.intro }
</code></pre>

<p>Something like that? I couldn't find anything, and it's hard to search on Google for something like "and not".</p>
