title: Abusing pattern matching
body: <p>I come from C# and find myself in love with the F# pattern matching syntax as it's simpler than C# <code>switch</code> and way more useful. I like to use it as much as possible, is there a performance or any other downside to using it in weird ways like in this example?</p>
  
  <pre><code>match 0 with
  |_ when a&lt;b -&gt; a
  |_ -&gt; b
  </code></pre>
