+// Set is an implementation of the concept of a set: a collection where all
+// values are conceptually either in or out of the set, but the members are
+// not ordered.
+//
+// This type primarily exists to be the internal type of sets in cty, but
+// it is considered to be at the same level of abstraction as Go's built in
+// slice and map collection types, and so should make no cty-specific
+// assumptions.
+//
+// Set operations are not thread safe. It is the caller's responsibility to
+// provide mutex guarantees where necessary.
+//
+// Set operations are not optimized to minimize memory pressure. Mutating
+// a set will generally create garbage and so should perhaps be avoided in
+// tight loops where memory pressure is a concern.
