PHP Array Syntax -> MailChimp Merge Syntax - 434 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!

Carriage return - 41 entries

I have some raw data from terminal output which uses carriege return for formatting. Carriage return sets the pointer to the first character on the line, and subsequent characters will overwrite what was there before. The challange is to simulate the terminal behaviour in vim. I'm kind of unsure if I should have skipped lines 9 and 15, since there might be some interesting solutions which are not that generic. Happy Golfing!
