Neat Little Trick for Creating Constructors with Defaults in Schema

export const withDefaults = <Self extends S.Schema<any, any>>(s: Self) => {
  const a = Object.assign(S.parseSync(s) as WithDefaults<Self>, s)
  Object.setPrototypeOf(a, Object.getPrototypeOf(s))
  return a
}

export type WithDefaults<Self extends S.Schema<any, any>> = (
  i: S.Schema.From<Self>,
  options?: AST.ParseOptions
) => S.Schema.To<Self>

export type NonEmptyStringBrand = B.Brand<"NonEmptyString">
export type NonEmptyString = string & NonEmptyStringBrand
export const NonEmptyString = nonEmptyString
  .pipe(
    S.annotations({ [TitleAnnotationId]: "NonEmptyString" }),
    fromBrand(nominal<NonEmptyString>()),
    withDefaults
  )
