Unable to parse 3.12 type params

[avamsi]

Code in question is:

def log_span[**P, R](func: typing.Callable[P, R]) -> typing.Callable[P, R]:
    ...

$ uvx fawltydeps -V

FawltyDeps v0.20.0

Thanks for reporting! Can you tell which Python version is being used to run FawltyDeps? I suspect that if FawltyDeps is running on <3.12 (and we're using the ast stdlib module to perform the parse) then FawltyDeps will be unable to understand >=3.12 syntax.

This is probably related to issue #460 , except that it concerns the maximum Python version that we support. It might be another argument for fully decoupling the Python parser from the underlying Python version.... 🤔

Apologies for the false alarm, uvx -p 3.12 fawltydeps indeed works fine!

I'm glad you found a straightforward workaround! I still want to keep this issue open to serve as supporting documentation for issue #460.
