There was a problem hiding this comment.
It would be good to test the non-serializable defining global, parameter, and local separately.

…ization errors in results (#7883) #7877 gave up when we couldn't serialize things, in various situations. But one of the cases, when we can't serialize the results, we checked AFTER we already "commit" the changes to the module. That is, we need to check for errors and stop if we find any, and only then apply execution results to the module, and we added a check that was after the application. To fix this, we need to be careful and know that if we will care about the serialization of the results then we cannot execute continuations, as they may end up needing to be serialized. Doing anything more precise would be significantly more complex.

They cannot be serialized.
This requires us to be able to "give up" when any serialization fails, adding
various code paths for that.
