This can make it difficult to force jsonpickle to use a specific backend, and catch errors, because the error will be suppressed and may not be raised by the subsequent backend. Calling `enable_backend(False)` will make jsonpickle immediately re-raise any exceptions raised by the backends.

This method loads a backend and sets up references to that backend's loads/dumps functions and exception classes. :param dumps: is the name of the backend's encode method. The method should take an object and return a string. Defaults to 'dumps'. :param loads: names the backend's method for the reverse operation -- returning a Python object from a string. :param loads_exc: can be either the name of the exception class used to denote decoding errors, or it can be a direct reference to the appropriate exception class itself. If it is a name, then the assumption is that an exception class of that name can be found in the backend module's namespace. :param load: names the backend's 'load' method. :param dump: names the backend's 'dump' method. :rtype bool: True on success, False if the backend could not be loaded.
