-/**
- * A collection of objects in which each object can occur only once.
- *
- * That is, for each object of the element type, the object is either considered
- * to be in the set, or to _not_ be in the set.
- *
- * Set implementations may consider some elements indistinguishable. These
- * elements are treated as being the same for any operation on the set.
- *
- * The default [Set] implementation, [LinkedHashSet], considers objects
- * indistinguishable if they are equal with regard to
- * operator [Object.==].
- *
- * Iterating over elements of a set may be either unordered
- * or ordered in some way. Examples:
- *
- * * A [HashSet] is unordered, which means that its iteration order is
- *   uspecified,
- * * [LinkedHashSet] iterates in the insertion order of its elements, and
- * * a sorted set like [SplayTreeSet] iterates the elements in sorted order.
- *
- * It is generally not allowed to modify the set (add or remove elements) while
- * an operation on the set is being performed, for example during a call to
- * [forEach] or [containsAll]. Nor is it allowed to modify the set while
- * iterating either the set itself or any [Iterable] that is backed by the set,
- * such as the ones returned by methods like [where] and [map].
