If you really want to allow any Python inside a f-string, can you

please at least explain in the PEP why you consider that it's a good thing?

Sigh. We've gone over this on python-ideas. Your objection is not new. I'm sure that later others will have exactly the same question than me. Is''t the purpose of the PEP to summarize a discussion to not have to repeat it again and again? Please, can anyone summerize the discussion (on allowing or not complex expressions in f-string) into a short paragraph in the PEP? I don't follow python-ideas and I don't want to subscribe.

But you can at least read the PEP. There is a whole section "Supporting full Python expressions" which explains this.
