I find this sad. In the JavaScript community the existence of Babel is very important for the long-term evolution of the language independently from the runtime. With Babel, JavaScript programmers can utilize new language syntax while being able to deploy on dated browsers. While there's always some experimentation, I doubt our community would abuse the new syntactic freedom that the PEP provided.
Then again, maybe we should do what Babel did, e.g. release a tool like it totally separately from the runtime. - Ł > On Oct 17, 2017, at 1:23 PM, Victor Stinner <victor.stin...@gmail.com> wrote: > > Hi, > > I rejected my own PEP 511 "API for code transformers" that I wrote in > January 2016: > > https://github.com/python/peps/commit/9d8fd950014a80324791d7dae3c130b1b64fdace > > Rejection Notice: > > """ > 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.
