Turn a ninja to case-insensitive [Nn][Ii][Nn][Jj][Aa] regexp! - 41 entries

I bumped into this in a dailywtf code: http://pastebin.com/QApa5ycS I didn't want to translate a string whenever I wanted to be [Ss][Aa][Rr][Cc][Aa][Ss][Tt][Ii][Cc] on slack, so I figured a script (python, sed, whatever) would be helpful. Well, or a few vim keystroke!

PHP Array Syntax -> MailChimp Merge Syntax - 440 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!
