[Python-ideas] Let’s make escaping in f-literals impossible

[Guido van Rossum]

I don't think we should take action now.

Would it make sense, as a precaution, to declare the PEP provisional for
one release? Then we can develop a sense of whether the current approach
causes real problems.

We could also emit some kind of warning if the expression part contains an
escaped quote, since that's where a potential change would cause breakage.
(Or we could leave that to the linters.)
