CPython has a magic number defined in `_bootstrap_external.py` that changes every time the bytecode is changed. RustPython is changing rapidly and I don't think we would like to update a magic number every change in the bytecode.\r\n\r\nI have a few suggestion:\r\n\r\n- Use the git commit as the magic: Would allow multiple runs with same `.pyc` without code changes.\r\n- Use a random number on main start: Would allow only the same run of main to use the same `.pyc`.","author":{"url":"https://github.com/palaviv","@type":"Person","name":"palaviv"},"datePublished":"2019-06-30T15:06:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/1090/RustPython/issues/1090"}
