<p class="MsoNormal"><span style="font-size:10.0pt;font-family:&quot;Arial&quot;,&quot;sans-serif&quot;">I was just doing some work with Template Haskell and I noticed that the AST does not have support for record puns and wild-cards. &nbsp;I know that these could be desugared into
 ordinary record patterns but I think that it would be more convenient for users (and also more consistent with the rest of the AST) if we provided direct support for them.</span><o:p></o:p></p>
