    v2 v3  
    1616* Deprecate `RR`, `Reals()`, and `RealField()` (`Reals(p)`, `RealField(p)` can probably stay). Replace `RR` by `RFP`.
    1717* Make it clear in the documentation that these parents represent sets of floating-point numbers—particular subsets of the dyadic rationals, augmented with special values such as ±∞ and equipped with well-defined, if peculiar, operations—, not the field of real numbers.
    18 * While we're at it, deprecate `RIF` and `RealIntervalField`. Rename them to something like `IF` (a common notation in interval analysis) and `RealFloatingPointIntervals`.
     18* While we're at it, deprecate `RIF` and `RealIntervalField`. Rename them to something like `IR` (a common notation in interval analysis) and `RealFloatingPointIntervals`.
    1919* Stop pretending any of these are fields (or even semigroups). Perhaps introduce a category of "approximate fields" (for lack of a better name).
    2020* After the deprecation period, consider making `RR` and `Reals` refer to/return `RLF` (or perhaps some new implementation that better models the "true" reals).
