Compare

See how Gosu compares to other Java Virtual Machine (JVM) languages:

	Gosu	Java	JRuby	Jython	Scala	Groovy	Clojure
Extensible type system (inject types into the type system)	✓
Static typing (type-safe at compile time)	✓	✓			✓
Easy transition from Java	✓	✓				✓
Closures (Gosu calls these blocks)	✓		✓	✓	✓	✓	✓
Reified generics (check generic types at run time)	✓
Modify existing types (no meta-programming)	✓				✓ *
No checked exceptions	✓		✓	✓	✓	✓	✓
Embeddable open compiler	✓		✓	✓	✓	✓	✓
Not Lisp	✓	✓	✓	✓	✓	✓

*Scala allows you to modify an existing type via Implicit Conversions, but it's pretty...well...complicated.
