Thanks, Marten, for including me.
1. I wouldn't trust the old code on `RealField(100)` (or much else for
that matter).
2. The QR decomposition for RDF/CDF matrices would be my alternate
suggestion. That's ''only'' 53-bit so that could be a downside if you
need more precision.
3. Or as Marten has suggested, all the old code is still available and
unharmed if you want to take the extra step to import it.
