That sounds very interesting; Do you have a write-up on this that you are willing to share?

This is the usual killer feature of something like rr. You debug, look at some variable: `p whatever`. You see that its value is wrong. You want to know where this wrong value came from, so you `watch -l whatever` and `rc`. Bam!
There are some bugs I would never have figured out without this technique. It feels like cheating.
Totally. rr is nothing short of a revolution in debuggin.
It’s not cheating, it’s technique!
