I've been writing several interdependent regex scripts to automate our #DNS, a strategy I'm sure I will most certainly not regret.
Very understandably, not one coworker has volunteered to review my PR so far. One of them glanced at it. I know this because I heard them say from their office down the hall "Uh oh! regex with backrefs in Ansible? This can't be good..." and then left no comment on the PR. And you know what - I can't blame them.
