Any exception that escapes from a hook gets reported along with a stack trace.

I added d2to1.util.nop_hook (prints that it was called) and d2to1.util.exception_hook (raises an exception) for debug/test use.

Rolling back to previous version of resolve_name; it's possible this can fail in the presence of a broken namespace package, but I want to make sure that's the case before trying to fix it.
