Zef Programming Language Zef is a dynamically typed object oriented and functional programming language developed primarily to demonstrate language implementation technique. Key Features Simple Dynamic Types. Variables and fields do not have static type. All dynamic types are subclasses of Object. int and double are objects. Integers and doubles are both are 64-bit. null is a synonym for 0. false
How To Make a Fast Dynamic Language Interpreter
Original Zef Interpreter The original Zef interpreter was written with almost no regard for performance. Only two performance-aware choices were made: The value representation is a 64-bit tagged value that may hold a double, a 32-bit integer, or a Object*. Doubles are represented by offsetting them by 0x1000000000000 (a technique I learned from JavaScriptCore; the literature has taken to calling t
