Unfortunately I can't remember the details at this point. There was something I couldn't figure out with the `new` function and heap allocation in general, and I also got frustrated trying to understand some things about the type system. I do know one thing about `new` was that it took me forever to figure out how to allocate anything on the heap at all, only to find a couple lines about `new` in the API docs. At least, I think that's what happened.

Sorry I can't be more specific.
