Out of curiosity is the term "internal" used at the spec level as well? It makes sense to mirror "external" but I figured these'd be called "any types" or... something along those lines. Anyway I'm just musing here.

The word "with" here makes me think that cats are replaced with animals, but I think you're intending the opposite here, so perhaps something like "s/with/for/"?

Wait sort of unrelated question on this, in the type section you can explicitly list the supertype and there's also
is_finalwhich say "no one else can subtype this". With the logic you're explaining below though that's not quite right is it? Anis_finalfunction type can still be subtyped so long as you align the parameters correctly?(totally unrelated to this PR I'm just trying to reconcile two different ways I've understood how subtyping is done in wasm)

Yeah I've seen it around, eg https://github.com/WebAssembly/gc/blob/main/proposals/gc/MVP.md#heap-types
Also turning an
externrefinto ananyrefis called "internalizing"

Yeah honestly I don't fully understand how all the dots connect in the way that the spec is written/defined, I just know what the intended behavior is.
FWIW, we don't supertypes and finality yet, but this code (and I suppose these docs) will need to be updated at that point.

is_finalfunction type can still be subtyped so long as you align the parameters correctly?And to be clear, yeah you can't subtype something (including a func type) that is declared final.
