Shouldn't this be flipped? That is, the seen type should be a subtype of the expected type?

No, in this case if I catch e.g. eqref, it would be valid and safe to overapproximate and have a pop anyref, but it would not be safe or valid to have pop i31ref, since the eqref I'm catching may not be an i31ref.

return Err{std::string("Expected pop of type ") + expectedType.toString()};
}
return Ok{};

Just to improve the output ordering. Adding the name doesn't affect whether the new parser can parse it.
