More helpfully, the Ascii object would raise *before* that - it would
raise on construction if it had any non-ASCII in it. Combining an
Ascii with a bytes results in a perfectly well-formed bytes; combining
an Ascii with a unicode results in a perfectly well-formed unicode.

But I'm not sure how (a) useful and (b) feasible this is. The only
real use-case I know of is Path objects, and there may be similar
tasks around numpy or pandas, but I don't know for sure.
