I don't (for the reasons raised before). But thank you for your explanation, it clarifies what you were proposing. And it does so within the *current* uses of the * symbol, which is good. But: 1. I'm not keen on extending append's meaning to overlap with extend's like this. 2. Your proposal does not generalise to generator expressions, set displays (without similarly modifying the set.add() method) or dictionary displays. 3. *fn(x) isn't an expression, and yet it *looks* like it should be, and in the current syntax, an expression is required in that position. To me, that suggests it would be hard to teach. [1] You can of course generalise Sjoerd's "from" proposal and then just replace "from" with "*" throughout. That avoids your requirement to change append, but at the cost of the translation no longer being a parallel to an existing use of "*". Paul [1] On a purely personal note, I'd say it's confusing, but I don't want to go back to subjective arguments, so I only note that here as an opinion, not an argument. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
