// The API for every set is:

//
//	// Len reports the number of elements in the set.
//	func (Set) Len() int
//
//	// Has reports whether an item is in the set.
//	func (Set) Has(T) bool
//
//	// Set inserts the item into the set.
//	func (Set) Set(T)
//
//	// Clear removes the item from the set.
//	func (Set) Clear(T)
