Note here that ideally the accesses to `math.config.predictable` and `math.types.Complex` in this factory mean that the resulting implementation of `sqrt` will depend on the `predictable` property of `math.config`, and so only be invalidated with that property changes, not on any change to `math.config`, just the way that the other possible implementation would only be invalidated if the implementation of `complex` on `Number, Number` were updated, but unaffected if the implementation of `complex` on `bigint, bigint` changed.

Looking at how other config properties might work, let's suppose that the `constants` property gives the numeric type that should be used for named constants (e.g., Number or BigNumber). We want `math.tau` to give a scalar entity, but we'd also like to record different possible entities for different types. Since we can't put properties on a number, we use a resolve function directly on the math object that takes the identifier to resolve:
