[Python-ideas] Re: PEP 472 -- Support for indexing with keyword arguments

Yes please. FWIW, IIRC the “bundle values in a single parameter” predates the demise of __getslice__. It probably was meant for dict keys primarily (no surprise there). The bundling would have been easier for the C API — __getitem__ is as old as Python there. On Sat, Jul 18, 2020 at 10:49 Steven

[Python-ideas] Re: Bringing the print statement back

-1 because it will introduce potential ambiguities and will generate stylistic battles between developers. It will also add questions when teaching python, having to explain the potentially different syntax one might find around. On Wed, 10 Jun 2020 at 01:07, Guido van Rossum wrote: > > In Pytho

[Python-ideas] Re: Pickle security improvements

Tragic! Pickle is relatively (?) fast and could be made more secure while making any performance regression due to additional security optional. Perhaps it is the objectives of pickle which are desirable: - serialize/deserialize arbitrary objects - binary representation Or perhaps the docs cou
