For what it’s worth, I initially thought it was a general fold function, using the magic of optional parameters and operator polymorphism to default to the most common reduction operation for a whole bunch of types. But it only took a few seconds to realize I was wrong. (Although I think this was added not long after new-style classes and the full dunder protocols, so I probably did have fun building a wrapper type that I could pass to sum and use it efficiently as a generic fold function against its will, it was pretty obvious that’s not what it was for.) _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/LTO3ETUL3HMGEEZ5SESIIFBKXC6QHJL4/ Code of Conduct: http://python.org/psf/codeofconduct/
