This is somewhat reminiscent of the argument that we don’t need any new magic
for str.format because you can (and people did) just use the existing version
that takes keywords and **locals() into it. The consensus there was that, even
though that makes the magic explicit, it makes it too magical, and should be
considered and anti-pattern, and we should try even harder for a better way to
eliminate it, and ultimately that’s where f-strings came from. And the explicit
magic didn’t even require frame-hacking in that case.
I’m not sure how much that parallel means (or even what it would imply if it
did mean a lot). I think I’m still -0.5, and the fact that you can get the same
effect if you’re willing to use CPython frame hacks doesn’t make me either more
or less negative.
