It's a passport to the JVM that has all the advantages of Python and few of its downsides. The philosophy is a unique combination of being incredibly developer friendly (kitchen sink APIs etc, every syntactical convenience you can imagine thrown in), but in every other aspect being ruthlessly Java-syntax compatible. You get both dynamic and static typing rolled in, super powerful AST transforms that give you static-compile-time metaprogramming capabilities other languages struggle to achieve. Yet it competes with Bash for single-line utility scripts.
