PHP Array Syntax -> MailChimp Merge Syntax - 427 entries

I recently needed to send an e-mail to our marketing department listing allowed merge tags for our MailChimp campaigns. The allowed merge tags were determined from a PHP array in one of our PHP classes. I transformed the PHP class to MailChimp's syntax and sent the e-mail. It was, however, a long, laborious process. I'm still fairly new to Vim and would love to see how an expert Vim user would tackle one of my own, real-world problems. Thanks and have fun!

Convert regular pandoc footnotes to in-line notes - 51 entries

Pandoc extends markdown by allowing footnotes, which are usually represented with a footnote identifier followed later in the document by the footnote itself. But Pandoc also allows inline footnotes without identifiers. How many strokes does it take to convert regular footnotes to inline notes?

I finally tested this locally using the Vimgolf vimrc and did a "gq" on the entire buffer as the last step. Apologies if I'm making a newbie mistake. First time submitter.)
