[Python-ideas] Re: PEP 671 (late-bound arg defaults), next round of discussion!

To clarify my statement about readability of the '@' prefix option… I think that its meaning is less clear if one doesn't already know what the syntax means. I think the code would be easier to skim, however, using that option after one does know its meaning. My favorite options are '@' or '?=' (tied), followed by ':=' followed by '=>'.
