Syntactic sugar to encourage use of named arguments

But this proposal has nothing to do with defaults. It’s entirely at the call, and allows deduplication of a VERY common call notation. I put together this script to quickly search for them, and found 17 examples in my own shed (which is a pretty small repository), and 3858 - that’s nearly four thousand - in the Python standard library. Allowing this to be deduplicated prevents desynchronization bugs.

It is very common. Running it on some other codebases:
