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

(do
    (print (factorial 7)))

Compliation flow:

Input(file) -> Parser -> Interpret(TODO)
  String       SExprs          IO
                     |->  Compile(TODO)
                              File 

Progress:

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

Problems:

• Parser can't detect (())) syntax error.
