 @WillAyd Would you want just one line in the Whatsnew enhancement section, or a whole subsection describing its use? @WillAyd @TomAugspurger Any other feedback? @WillAyd Ping; fixed the minor feedback. Would you mind giving me an example of the Subsitute decorator so that I can use it in my followup PR? Thanks @MaxVanDeursen!
