Test for code serialization operations.
Define a function, serialize it, then deserialize it back to an actual function. Also ask for its dependencies for display later.

This simply runs some functions to make sure there isn't a crash. Once we gain the ability to capture output in a transcript, it can be modified to actual show that the serialization works.
