Review comment:
The CompareOptions weren't really options, it was just a facade in C++
over the underlying functions (somewhat similar to ArithmeticOptions in fact).
When the options classes were "upgraded" to make them serializable,
CompareOptions was deemed redundant and mostly removed.
Looking at it now, I can see the argument for four separate functions for
consistency, but that means we probably don't want/need BetweenOptions or any
enum at all.
