-		Candran is a dialect of the Lua 5.3 programming language which compiles to Lua 5.3 and Lua 5.1/LuaJit. It adds several useful syntax additions which aims to make Lua faster and easier to write, and a simple preprocessor.
-		Unlike Moonscript, Candran tries to stay close to the Lua syntax, and existing Lua code can run on Candran unmodified.
