// General hints on defining types with constraints or invariants | |
// | |
// Just as in C#, use a private constructor | |
// and expose "factory" methods that enforce the constraints | |
// | |

// | |
// If you want to use the record and DU types, the whole type becomes | |
// private, which means that you also need to provide: | |
// * a constructor function ("create"). |
