It's much more true now than it has been in over a decade. People have largely moved away from python 2.7 and after that it's pretty easy to keep pace. There's a lag, but it's no longer decades. > Adding these functions > to the stdlib would mean that *only* people using Python 3.8+ would > have access to them (and in particular, library authors wouldn't be > able to use them until they drop support for all versions older than > 3.8).

And if library authors want to support older versions they'll have to vendor this into their own code, just like always. This seems totally irrelevant to the discussion. And it's of course irrelevant to all the end users that aren't writing libraries but are using python directly. > As with everything, it's a trade-off.

Putting it in a library virtually guarantees it will never become popular. And because we are talking about new methods on str, a library that monkey patches on two new method on str won't become popular for obvious reasons. Plus it's actually impossible: >>> str.foo = 1 Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: can't set attributes of built-in/extension type 'str' So this can't really be moved into the standard library or be implemented by a library in a nice way. / Anders _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
