> Between fastintfloat_alt.patch and fastint5.patch, I prefer fastintfloat_alt.patch which is much easier to read, so probably much easier to debug. I hate huge macro when I have to debug code in gdb :-( I also like very much the idea of *reusing* existing functions, rather than duplicating code.
I disagree.
fastintfloat_alt exports a lot of functions from longobject/floatobject, something that I really don't like. Lots of repetitive code in ceval.c also make it harder to make sure everything is correct.
