why chaining order of nullish is optional().nullable()?

[p10ns11y]

I would like to know the reasoning behind the decision why nullish's chaining order is optional().nullable()?

I think if the order is nullable().optional() then it would play nicely with required

Use case:

const schema = z.object({
  nullishProp: z.string().nullish(), // optional().nullable()
  anotherProp: z.number(),
})

The latest code will not make nullishProp as required prop when we do schema.required({ nullishProp: true })

If we had nullable().optional() for nullish then schema.required({ nullishProp: true }) make nullishProp required and allow null value as well

This is a very interesting thing that you have found. I'm not sure if this is intended behavior or not. Feel free to submit a PR for this.
