I favor a dual-mode approach. I think the existing behavior is best for the
conversion of existing modules, because it's easy to interactively verify
the generated code. Once that's done, long-term maintenance definitely
favors a more centralized format.

It's not about mixing bytes and text -- it's about
writing polymorphic code that will work on either
