Of course it has. I had Perl 4 on my Debian box for a decade after Perl 5 was released, because various apps had scripts or something that wouldn't work or weren't tested on Perl 5. Ditto, point releases of Perl 5 on Debian and MacPorts. Python is no different, except for porting from Python 2 to Python 3. > I almost never have to modify my old code. I can beat that: I have never yet modified code written for Python 3 because something broke when I upgraded Python. I've modified (mostly added, but sometimes rewritten) a lot of code because suddenly it was fun rather than painful to write something (definitely comprehensions and f-strings had that effect). When you're writing for fun (which is true of the people who work on core Mailman and mostly for Postorius; HyperKitty was pretty much all done on Red Hat's tab IIUC), that's really important to keeping the project moving. > I'd recommend you use Perl, but everybody knows Perl is dead :-) The premature reports of Perl's death are not why I don't like reading Perl.

That doesn't mean that security fixes in libraries or new web protocols like DMARC won't break your code or pollute its environment, which is the "because 2020" issue in MM2. AFAICS, it's the same deal for those languages -- you're going to have to deal with security issues in libraries, not language translators, that are abandoned. I just don't see a big win here, unless you're able to restrict the libraries you use to a very limited scope. But that makes the 2020 problem for Python much less painful too. > > Something that basically isn't broken, like MM2, wouldn't > > need to be fixed "because 2020". MM2 doesn't need to be fixed "because 2020." It needs to be fixed because of the hordes of orcs on the Internet. 2020 may make that somewhat harder. On the other hand, 2020 also makes one heck of a lot of software more fun and powerful because Python 3 exists.
