title: R dplyr - distinct accross all columns
body: <p>Is there a way to specify dplyr::distinct should use all column names without resorting to nonstandard evaluation?</p>
  
  <pre><code>df &lt;- data.frame(a=c(1,1,2),b=c(1,1,3))
  
  df %&gt;% distinct(a,b,.keep_all=FALSE)          # behavior I'd like to replicate
  </code></pre>
  
  <p>vs</p>
  
  <pre><code>df %&gt;% distinct(everything(),.keep_all=FALSE) # with syntax of this form
  </code></pre>
