    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.

          Using LLMs to build dozens of prototypes and test them before committing to a direction is one of their great strengths.

          You no longer have to guess which paths will pay off. Have the LLM test them all, then go back and write the best one how you wanted to.

            Sucks when four out of twelve are flawed and you rule out the top 2 best solutions and 5 useful test cases you could learn from by just spray and praying... But at least it was fast!?
