As is already a keyword from with-as and except-as. Perhaps for compatibility “as” is allowed but discouraged as a variable name, and it’s only interpreted as a keyword when followed by an expression and a colon. > 3 - Most of the example (and you show it yourself with flask) are > already possible with a more verbose syntaxe based on decorators Yup, a more terse syntax puts the programmer’s focus on the right things. > 2 - This will be tempting to use for callbacks and chaining things, > leading to the nesting hell we tried very carefully to avoid fom other > languages. The example for sorted is also kinda twisted. I do agree as-do could be easily used for callbacks. Could you please clarify what you mean by nesting hell? Is it better to use as-do where you’d normally pass your own instantiation of a class you create that implements a protocol? It’s always possible to simply pass a bound method of a class you create yourself if you want to keep state. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
