@neauoire https://github.com/scrottie/Code-Splice for injecting inspection, and for in-lining method calls in a certain not-dead-yet language. I wrote a conference lighting talk that I never gave that continuously pulled from github, parsed the diffs, and spliced changes in to the running program. Wasn't able to keep up with maintaining that and afaik no one else really used it for anything so long dead.
@scrottie thanks! I'll dive in. Never heard of something like this before
