/**
 * Will set type of property to `null | undefined`.
 *
 * Useful for cases when you have to explicitly exclude
 * specific property from type.
 *
 * **Example:**
 * ```ts
 * class A {
 *   @Option()
 *   prop1: string;
 *   @Option()
 *   prop2: string;
 *   @OptionNotPresent()
 *   prop3?: null | undefined; // This prop should be excluded!
 * }
 *
 * class B {
 *   @Option()
 *   prop1: string;
 *   @Option()
 *   prop2: string;
 *   @Option()
 *   prop3: string;
 * }
 *
 * type AorB = A | B;
 * ```
