研究方向
Investigate the type inference issue with expectMsgType[T] in Scala 3, starting from the discussion in PR #29956. Look at the testkit source code in the akka repository, particularly the expectMsgType implementation. Consider whether the issue is related to Scala 3 changes in type inference or a specific interaction with Scalatest. No maintainer has clarified the scope or expected outcome.
