If perf is bad, I'll put this behind a debug cfg I guess

Overall result: ❌ regressions - no action needed

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

More checking is good. r=me, I'll let you decide how to address the suggestions.

Note: this is a weird name for a method returning bool.

(But pre-existing, so no need to change anything in this PR.)

I will not change it in that case 😅

Seems like the Closure and Coroutine branches could be merged, the types are the same. Only the error message differs, but it could be changed to "closure/coroutine field has the wrong type".

No, they differ with how they handle their args. See the as_coroutine and as_closure.
