I'm not so sure that it only makes sense for named arguments. I think it works for arbitrary expressions too:
f'{len("NOBODY expects the Spanish Inquisition!")!d}'
ought to return
'len("NOBODY expects the Spanish Inquisition!")=39'
which I can see being very useful in debugging expressions.
Absolutely! I can't imagine doing *hugely* complex expressions, but consider: print(f"{request.args!d}") Technically that's an "arbitrary expression" and is most definitely not a named argument, but it's the sort of thing where you really do want the tag to say "request.args" and not just "args" or anything like that. Ideally, I'd like to be able to write this as: dump(request.args) and have it pick up both the string "request.args" and the value of request.args, but the f-string variant is absolutely okay with me as a partial solution.
