Speaking of poor programming practices, how about copy-pasting code without understanding it? Notice the author's mention of how many packages with -Ofast trace their lineage back through this comment: # Initially copied from # https://github.com/actions/starter-workflows/blob/main/ci/python-package.yml # And later based on the version jamadden updated at # gevent/gevent, and then at zodb/relstorage and zodb/perfmetrics Although the linked config was modified 2 years ago to removed the unsafe math options[1], the copy-paste propagated before then. Naturally anyone asking CoPilot, ChatGPT, or other modern LLM-based interface for config code will likely get something based on this, with the problematic -Ofast option included.
