// all references to string in this scope now enforce minLength: 1
const $ = scope({
	foo: {
		// has minLength: 1
		bar: "string"
	},

})

// has minLength: 1
const s = $.type("string")

const types = scope({
	ArraySchema: {
		"items?": "Schema"
	},
	Schema: "TypeWithKeywords",
	TypeWithKeywords: "ArraySchema"
}).export()

const t = types.Schema.pipe(o => JSON.stringify(o))
