Schema + constructors + domain ops pattern for branded types

const schema = Schema.Number.pipe(Schema.brand('SlideNumber'))

export type SlideNumber = typeof schema.Type

export const SlideNumber = {
  schema,
  new: Brand.nominal<SlideNumber>(),
  next: (current: SlideNumber): SlideNumber => SlideNumber.new(current + 1),
  allBetween: (first: SlideNumber, last: SlideNumber): SlideNumber[] => {
    return new Array(last - first + 1).fill(0).map((_, i) => SlideNumber.new(first + i))
  },
}
