BoxLang 1.14.0 ships something that JVM developers have wanted for a long time: a true first-class Set type baked directly into the language. Not a wrapper you reach for manually, not a createObject( "java", "java.util.HashSet" ) incantation you paste from a Stack Overflow answer years ago. A real BoxSet with literal syntax, operator overloads, a full functional pipeline, change listeners, JSON serialization, and deep Java interop.
