Worked on the facebook/pyrefly repository to address a type parameter display issue affecting ParamSpec in hover lists, ensuring accurate representation in both default and LSP modes. The solution involved updating quantified.rs and display.rs to align hover output with Python syntax, specifically adding the ** prefix to ParamSpec declarations. To prevent future regressions, a dedicated unit test was introduced to validate correct rendering in both contexts. This targeted fix, implemented using Rust and leveraging expertise in type systems and unit testing, improved the developer experience by resolving confusion when inspecting generic signatures and was merged as part of PR 3594.
