I *think* you are trying to find a syntax for "code blocks" like Ruby has, but I'm not sure. Your examples are a little confusing to me (possibly because you have at least three separate suggestions here, "as" blocks, a mysterious "do" keyword I don't understand, and partial application using % as argument placeholder).
Many people have tried to find a syntax for code block expressions, none have succeeded. Please note that being an *expression* is critical. We already have syntax for code block statements, it is the "def" keyword. You probably ought to spend a few days searching the mailing list archives for previous discussions before you get your hopes up. Before I spend any more time on this proposal, I'll skip right to the end of your post: On Wed, Jul 25, 2018 at 01:07:50PM -0400, James Lu wrote: > I’m not totally sure of practical uses, If you don't have practical uses, this proposal has ZERO chance of being accepted.

I don't see how it can be more convenient than: function(another_function) -- Steve _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
