I'm pretty sure this is semantically equivalent to my original code,
but I gave it a try anyway. FWIW, it doesn't work, either. :-}

I'm starting to believe it, but... I thought that one of the
benefits of making print a function was that it *could* be globally
replaced. So far I've had no luck injecting a custom print
replacement into other modules. Is this really not possible?
