It takes courage to admit failures like this! I think this is a good call. It echoes the experiences with Unladen Swallow and Pyston. Despite what people may think, CPython really isn't slow, given the large set of constraints on the implementation.

Hi,

I rejected my own PEP 510 "Specialize functions with guards" that I wrote in January 2016: https://github.com/python/peps/commit/c99fb8bf5b5c16c170e1603a1c66a7 4e93a4ae84 "This PEP was rejected by its author since the design didn't show any significant speedup, but also because of the lack of time to implement the most advanced and complex optimizations." I stopped working on my FAT Python project almost one year ago: https://faster-cpython.readthedocs.io/fatpython.html Victor
