Here is the proposal we have worked on (Pablo and I). I've added Larry as co-author given that a good chunk of the content and the idea comes from his PEP. Larry, if you don't want to appear as such please let us know. Thanks! Rendered content:

Not so fast. I think a PEP is still needed. This change has more repercussions than argument clinic, e.g. it affects 3rd party tooling and bytecode. On Jan 19, 2018 17:00, "Terry Reedy" wrote: > On 1/19/2018 4:49 PM, Mario Corchero wrote: > >> I am happy to put some work into
