Constructor. The optional 'locals' argument specifies the dictionary in which code will be executed; it defaults to a newly created dictionary with key "__name__" set to "__main__". The syntaxerror callback can be set at any time and will be called on a caug

        The syntaxerror callback can be set at any time and will be called

        the repl can be instantiated after the interpreter (which it
        necessarily must be with the current factoring) and then an exception
        callback can be added to the Interpreter instance afterwards - more
        specifically, this is so that autoindentation does not occur after a
        traceback.
