And the "don't fix what ain't broke" people are well supported, by explicit policy and by the personal dedication of developers like Victor Stinner. > In this regard the existence of Python 3 is a disadvantage, not an > advantage for my new code, regardless of how much better a language > or dev environment it may be. You mean, at this very instant. Pay now, profit later is the definition of "investment." In the past, while I'm sure you worked real hard, you didn't have to pay the price of the *community's* investment because you were free to start new projects in the way best fitted to current features. Now, with a large codebase to maintain and extend, you have to share the community's costs by either living with Python 2, which won't improve from now on, or shifting to Python 3, which entails big porting costs for many projects.[1] Or you can participate in a new project to fork from python.org and continue development of Python 2. You have a wealth of choice there. The problem[2] is that you're not getting a free ride on the fast track this time. Well, that party was nice while it lasted, but now it's over. The next party is going to be at the Python 3 Lounge, and you're invited. Sure, you gotta get up and go to work tomorrow, but Friday's comin'! Footnotes: [1] But I can't say it's obvious that they're huge on average. There's clearly a lot of variance in porting costs. [2] This is a community problem; it's not something you did to yourself. But it's also been judged unavoidable if Python is to continue to grow. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
