Ah yes, I forgot that.

I had in mind just bitwise copying them. But I guess that slightly
defeats the purpose of such fields, and could conceivably be a bit evil.
I might rethink it as just a record-copy, since plain records have none
of those questions. But that'd need at least `record?' down in C code
for a type check, so it might have to wait until most of the record
stuff is in C.
