<div dir="ltr">As for the original question, I don't see any reason the various built-in method combination could not have been defined to support :before and :after methods. But the way they are defined is consonant with the short form of define-method-combination, which implies that the several built-in method combinations would typically be implemented using short form d-m-c. So the scope of the original question probably should be expanded to include short form d-m-c.</div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, May 19, 2017 at 6:20 PM, Steve Haflich <span dir="ltr"><<a href="mailto:shaflich@gmail.com" target="_blank">shaflich@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">You're apparently confusing two different meaning of "standard".

<br>
</span>If you are defining the method combination, you have way more freedom<br>

Basically, you can do it yourself.<br>
