+1 for &amp;; I think it reads really well, and I think it&#39;s silly to go for consistency with C (especially when we can&#39;t have | anyway). I know some beginners struggle with function application ordering in Haskell because they find it unnatural and you have to backtrack more when reading such code. I&#39;m sure those people would like (&amp;).<br>

<br> -1 for |&gt;; there are reasons I rarely use &gt;&gt;&gt; for flip (.), and I wouldn&#39;t use |&gt; either.<br>
