So actually my question is: What should happen when the annotation is already a string literal?
The PEP answers that clearly (under Implementation):
If an annotation was already a string, this string is preserved verbatim.
Oh sorry, I was looking for a spec, so I somehow assumed I can ignore the gory implementation details just like I routinely ignore things like headers and footers of emails.
There's two thing I don't understand here:
- What does it mean to preserve the string verbatim? No matter how I read it, I can't tell if it's with quotes or without.
Maybe I'm missing some context.
