For now it works but i dont really like that i use ParseResult, i mean is necessary but i think i will try to make it cleaner so that i can just directly use like parse and pass tath into evaluate, that would require to move the main evaluate funciton into evaluate_tree or something and evaluate takes the arena, uses evaluate_tree and frees the arena, will try that the next commit but for now this version works perfectly.
