-REPL:
-
-1. read user input
-2. parse it into an ast
-3. reduce the ast to the minimum possible form
-4.
-
-every expression is a binary tree, except () which can be interpreted by changing the
-structure of the tree.
-
-operators and operand are both expression (tree nodes).
-
-operators always need 2 operand  (not leaf node)
-operand need 0                   (leaf node)
-
-evaluation of operand return the operand
-evaluation of operator, evaluate his childs, perform the operation on them, return the result
