 LLJS
 ====
 
-LLJS (formerly known as *JS) is a typed dialect of JavaScript that offers a C-like type system with manual memory management.
-It compiles to JavaScript and lets you write memory-efficient and GC pause-free code less painfully, in short, LLJS is the bastard child of JavaScript and C.
-LLJS is early research prototype work, so don't expect anything rock solid just yet.
-The research goal here is to explore low-level statically typed features in a high-level dynamically typed language.
-Think of it as inline assembly in C, or the unsafe keyword in C#.
-It's not pretty, but it gets the job done.
