+##### Our syntax support the most basic subset of Rust:
 - Primitive types such as i32 and boolean
 - Functions with the primitive return types
 - let, if, if else, while, assign, return
 - Precedence of operands by dividing them into arithmetic, conditional and logical operands.
 - Possbility for ArCode (addition and subtraction) to have precedence over FactorCode(multiplication and division) by parenthesized precedence
 
-##### Future implementation
+##### Future implementation:
 - Better error handling with location information
 - More types
 - Nestled functions
