Message 285680 - Python tracker
Raymond Hettinger: "This should not go in without Stephan Krah's approval. This code is finely tuned and carefully arrang" Sure, that's why I opened this issue. Serhiy Storchaka: "See msg207652 in issue20177." Oh, I didn't know that Stefan Krah already gave his opinion. Since the performance impact is unclear, I prefer to close this issue. I will come back if argument parsing is more clearly identified as a performance bottleneck.
