<p style="margin:1.2em!important">In <code><span style="font-size:10.0pt;font-family:Consolas;border:solid #EAEAEA 1.0pt;padding:0in;background:#F8F8F8">@escaping</span></code> arguments, adding
<code><span style="font-size:10.0pt;font-family:Consolas;border:solid #EAEAEA 1.0pt;padding:0in;background:#F8F8F8">self.</span></code> won’t add enough evidence that it actually creates a closure with capture.<br>
Even in non-escaping context, I find plain method references odd:<code><span style="font-size:10.0pt;font-family:Consolas;color:#333333;border:solid #CCCCCC 1.0pt;padding:6.0pt;background:#F8F8F8"><o:p></o:p></span></code></p>
