I disagree. I know there's a huge focus on The Big Libraries (and wholesale migration is all but impossible without them), but the long tail of libraries is still incredibly important. It's like saying that migrating the top 10 Perl libraries to Perl 6 would allow people to completely ignore all of

I think strftime / strptime support is a low-priority concern on this topic, and can probably be discussed independently of the core nanosecond support. Regards Antoine. On Thu, 11 Dec 2014 11:14:27 -0800 Guido van Rossum wrote: > Another issue to consider here is that parsing and printing sh

2014-12-11 Thread Guido van Rossum
Another issue to consider here is that parsing and printing should be symmetrical. The %f format gobbles up exactly 6 digits. Finally, strptime and strftime are not invented by Python, the same functions with (mostly) the same format characters are defined by other languages. Is there not a single

Thanks Stephen elaborating on the process. and apologies, I was dismissing the last point only half jokingly. I read the comment for strftime / strptime in the report as meant to remember to implement it. It seems picking a new format letter (or keep using "%f" if acceptable) that would accept
