    Excited to see if there is a path to getting this in the mainline compiler

      Talking with them presently! This specific set of changes won't get in (LLM written, little to no thinking through of the broader design), but I am hoping something like it shows up sometime.

        Never thought of it like this, that synthetic code doesn't need to get into a codebase for it to benefit from the discussion around what was encoded with LLM.

          This is why LLM generated PRs are great… they should just be opened as issues instead.

            That's a good point. I've gotten a few PRs to a project I work on, where the general idea is good, bit the actual code has serious issues, so I end up just implementing the idea myself in a better way.

            It's a decent idea until 12000 bots start spamming a repo with janky code and poorly founded really complex suggestions for cs students to spray and pray resume padding.
