Beschreibung
Description
This code is, as far as I understand, meaningless. It should not be accepted, even though I think it is just a no-op. I bet it is now parsed because of isolated conformances but then just silently dropped further down the line.
Reproduction
class Base {
}
class Derived: @MainActor Base {
}
Expected behavior
This should produce an error.
Environment
Apple Swift version 6.3-dev (LLVM d402ab9729f318e, Swift 2de856568572fc0) Target: arm64-apple-macosx26.0
