Great findings, I can reproduce both that redefining again after loading, or running with Seems like precompilation may be connected, where the old stuff isn't invalidated if it hasn't already been loaded? |

That would explain why As an awful hack, I could call the latter too, then at least they'd agree. lol |

Hmm, I can reproduce on 1.5 too now. Not sure how I wasn't earlier. |

Darn. Because we can repro on Julia 1.5.0, we won't be able to bisect. |

BTW, you should probably update your comment in the 265 issue to reflect that you can reproduce on 1.5.3. |
