描述

There's a bunch of warnings that Dotty emits, e.g. type tests that cannot be checked at runtime.

I suspect many of them can be resolved in a way that are compatible with Scala 2.

研究方向
The issue mentions cleaning warnings from Dotty (Scala 3) but provides no specific examples. First, investigate the current warnings by building the project with Scala 3. Search the codebase for common warnings like unchecked type tests or match exhaustiveness. Check if there are any existing PRs or branches addressing this. Consider commenting on the issue to ask for clarification on which warnings are prioritized.
