cfallin opened PR #14012 from cfallin:trace-exn-ty to bytecodealliance:main:
I believe this is unreachable in practice because aggregate Wasm types can hold only
exnref(/noexnref); the Wasm type system does not have a concrete exn as a separate type that could appear within an aggregate. Nevertheless, for completeness, we should have this match arm.Pointed out by Alex (thanks!).
