Message:

Not sure why we copy in the return values all the time, but we do. This prevents an unused error from appearing when the library is being compiled (shows up about 4 times right now). Switching some passes around might have also solved the problem, but I think we should be generating normalized code instead of mixing in the normalization and code generation.
