- A non-thread-safe helper class to ease implementing singletons.
- This should be used as a **decorator** -- not a metaclass -- to the class that should be a singleton.
-
- The decorated class can define one `__init__` function that takes an arbitrary list of parameters.
-
- To get the singleton instance, use the :py:meth:`instance` method. Trying to use `__call__` will result in a `TypeError` being raised.
-
- Limitations:
-
- * The decorated class cannot be inherited from.
- * The documentation of the decorated class is replaced with the documentation of this class.
