I rejected my own PEP 511 "API for code transformers" that I wrote in
This PEP was rejected by its author.
This PEP was seen as blessing new Python-like programming languages
which are close but incompatible with the regular Python language. It
was decided to not promote syntaxes incompatible with Python.
This PEP was also seen as a nice tool to experiment new Python features,
but it is already possible to experiment them without the PEP, only with
importlib hooks. If a feature becomes useful, it should be directly part
of Python, instead of depending on an third party Python module.
Finally, this PEP was driven was the FAT Python optimization project
which was abandonned in 2016, since it was not possible to show any
significant speedup, but also because of the lack of time to implement
the most advanced and complex optimizations.
