(fun factorial [x]
    (if (<= x 1)
        1
        (* x (factorial (- x 1)))))

(def times 7)
(do
    (print (factorial times)))

Compliation flow:

Input(file) -> Lexer -> Parser -> Interpret
  String       Token     Expr         IO
                              |-> Compile(TODO)
                                     File 

Progress:

• Lexer & Parser
• Syntax checker & Type checker
• Interpreter
• Compiler

Problems:

• Parser only detect the first error.
• Parser can't detect (())) syntax error.
