Hi Alexandre Thank you for your post.
In PEP 505 the context for the example being discussed is: > Some of these are shown below as examples before and after converting to use > the new operators. You wrote: > So yes, *strictly speaking* the two chunks of code are not exactly the same. I see nothing in the context that indicates that given suitable (Python) context, the before and after expressions give different values. I assumed the before and after values were intended to be the same. By the way, I think that even without your *strictly speaking*, the two chunks of code are not exactly the same (in that they can give different values from identical inputs). > In practice, they'll act the same way given sensible inputs. For me, the truth or falsity of this statement requires more than the peep-hole view of the code supplied by the PEP. Your argument for its truth certainly looked beyond the PEP. I think lack of clarity can mislead, and prevents the PEP performing properly one of its key functions === https://www.python.org/dev/peps/pep-0001/#what-is-a-pep The PEP should provide a concise technical specification of the feature and a rationale for the feature [being proposed]. === and so is a bug in the PEP. Fixing it will help the progress of the PEP. Where to report the bug? Either to Steve Dower, or raise an issue on github. https://www.python.org/dev/peps/pep-0001/#reporting-pep-bugs-or-submitting-pep-updates Steve's already been emailed on this. We're waiting to hear back from him. -- Jonathan _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
