Oh, I see.  That seems like kind of a problematic requirement,
unless we leave some datatype around that's intentionally not
ever going to be converted.  For datatypes that we do convert,
there shouldn't be any easy way to get to a hard error.

I don't really quite understand why you're worried about that
though.  The hard-error code paths are well tested already.
