/**
* Allows creating a union type by combining primitive types and literal types
* without sacrificing auto-completion in IDEs for the literal type part of the
* union.
*
* Currently, when a union type of a primitive type is combined with literal
* types, TypeScript loses all information about the combined literals. Thus,
* when such a type is used in an IDE with autocompletion, no suggestions are
* made for the declared literals.
*
* This type is a workaround for {@link
* https://github.com/Microsoft/TypeScript/issues/29729
* Microsoft/TypeScript#29729}. It will be removed as soon as it's not needed
* anymore.
