So please implement this small piece of Python code in C++ so we can
compare the idioms:

    import sys, time

    class MyLogger:
        def __init__(self, write):
            self.write = sys.stderr.write

        def register_writer(self, write):
            self.write = write

        def log(self, text):
            self.write("{} {}\n".format(time.time(), text))

    class MyApp:
        def __init__(self, logger):
            self.logf = open("thelog.log", "a")
            logger.register_writer(self.log_write)

        def log_write(self, text):
            self.logf.write(text)
            self.logf.flush()
