That would be expensive to get, wouldn't it? The main point of binary
I/O is to be fast, so I'm not excited about an expensive conversion.
What if we just defined the binary format as being identical to the text
format, ie, the enum label? A bit silly but at least it would eliminate
the gotcha that binary I/O fails.
