Very happy to see this new alpha version of Fable being released 🥰 The Python target is getting a well-deserved upgrade.
🚀 Fable 5.0.0-alpha.14 is out!
This one has a big focus on Python and adding support for Nullness to Fable (both your project and dependencies needs to be written with nullness in mind for it to work)
To benefit from all the new features you need to use Fable.Core beta too

Todays summary after a 12-hour session. Most Python developers never touch meta-classes. Most F# developers never think about Python descriptors, at least not at the class attribute level. Doing both simultaneously while solving circular dependency problems in a compiler context! 😅 Time to sleep 😴
