title: Apply lambda to an object
body: <p>Let say I have a variable and lambda defined somewhere</p>
  
  <pre><code>phone = "1(234)567-89-01"
  lambda = -&gt; { gsub(/[^0-9]/, '') }
  </code></pre>
  
  <p>How can I apply lambda to the phone to get <code>12345678901</code>?</p>
  
  <p>P.S. I know I can go with the following approach:</p>
  
  <pre><code>lambda = -&gt; (arg) { arg.gsub(/[^0-9]/, '') }
  lambda.call(phone)
  #=&gt; "12345678901"
  </code></pre>
  
  <p>But I want to be laconic.</p>
