I thought Polonius would be part of the 2024 Edition, and was sad not seeing being mentioned at all. Good to see its still being worked on.

Afaik they're hoping to land it on nightly in 2025H1.

Between that, work on the next-generation trait solver and promoting parallel frontend, there's some stuff to look forward in the compiler this year.
