+/**
+ * Converts a union type to an intersection type.
+ *
+ * This type takes advantage of TypeScript's inference and distributive conditional types.
+ * It starts by using a mapped type to distribute the conditional type over the union type `T`.
+ * For each distributed type, it creates a function type with the type parameter as its argument.
+ * Then, it infers the intersection type `U` by analyzing the compatibility of the function types.
+ * The process results in an intersection type representing the combination of all distributed types.
+ *
+ * @template T - The union type to be converted into an intersection type.
+ *
+ * @returns The intersection type created from the union type `T`.
