From: mtshiba/pylyzer#115

Starting with Python 3.12, the use of strings within f-strings is permitted.

Reference

However, the current parser implementation does not seem to allow the use of same quoting type strings within f-strings.

f"{"hello"}"

results in the following parsing error:

invalid syntax. Got unexpected token 'hello' at row 1 col 5

Yes, we are not following up this feature yet, sorry. RustPython is considering to move on Ruff's python parser. If it is successful, I doubt RustPython team will put effort to this repository anymore.

This issue also affects a project I'm working on. If the decision is to move to the ruff python parser then it would be nice to get some guidance on migration, if anyone has time to support with that.

Ah, another f-string that is failing is this

f'{' f'}'

I guess I just don't bother with test_fstring for now.
