IMHO way too complicated, and too few people understand coercion as it

I would argue that the result would be *more* predictable and certainly
more accurate than now.
Coercion must always be from higher precision to lower precision, this
is the only structure-preserving map.
Sure, my proposal doesn't change this.
Essentially, my proposal boils down to: when doing an operation on
arguments with differing precisions, *first* do the operation and *then*
lower the precision instead of the other way around.
