Comment (by mmezzarobba):
Most of the changes look good to me, but I don't like the new description
of `RealLiteral.numerical_approx()`: as far as I understand “real
literals” are exact decimal numbers, so converting one to a `RealField`
element with d·log₁₀ 2 bits of precision doesn't really “change its
precision” to d decimal digits.
And—just wondering, I have nothing against that choice—is there a reason
why you didn't put the generic implementation directly in `Element` (and
put code to convert non-Elements to Elements before calling it when
necessary)?
