Add a public method `destroy` on Translator to reset properties and free memory
if you mean `__destructor`, the answer is no, because the __destructor is not called due to circular reference.
If you suggest the name `destructor`, I'm not aggre, because this method does not destruct anything. @fabpot is right, `reset` is better name.
