title: Idiomatic clojure map lookup by keyword
body: <p>Say I have a clojure map that uses keywords as its keys:</p>
  
  <pre><code>(def my-car {:color "candy-apple red" :horsepower 450})
  </code></pre>
  
  <p>I know that I can look up the value associated with the keyword by either using the keyword or the map as a function and the other as its argument:</p>
  
  <pre><code>(my-car :color)
  ; =&gt; "candy-apple red"
  (:color my-car)
  ; =&gt; "candy-apple red"
  </code></pre>
  
  <p>I realize that both forms can come in handy for certain situations, but is one of them considered more idiomatic for straightforward usage like shown above?</p>
