I proposed something simpler, but nobody tried to implement it. Instead of calling the long and complex PyArgParse...() functions, why not generating C code to parse arguments instead? The idea looks like "inlining" PyArgParse...() in its caller, but technically it means that Argument Clinic generates C code to parse arguments. But I have worrying about it. If we do it for all function, it makes Python binary fatter, consume more CPU cache. Once CPU cache is start stashing, application performance got slower quickly.

Now, I'd like to see benchmark numbers for that before I believe it. Macro benchmarks, not micro benchmarks! wink
