Message 65111 - Python tracker (original) (raw)

I'm not sure how this matters. The order of evaluation is the same, the BUILD_SET implementation just hashes the evaluated items in a different order. You can't really rely on that particular order as it's tied closely to the stack representation CPython uses. I also see no practical reason -- or even practical way -- to abuse the hashing order. But you have given me an idea on how to improve some of the code in the BUILD_*_UNPACK opcodes, hmm.
