        This is a workaround of a Python weakref bug.

        `obj_weakref` is instance returned by `weakref.ref`,
        `str(obj_weakref)` is buggy if the original obj overrides __getattr__, e.g:

            class MyConfig(dict):
                def __getattr__(self, x):
                    return self[x]

            obj = MyConfig(offset=5)
            obj_weakref = weakref.ref(obj)
            str(obj_weakref)  # raise error: KeyError: '__name__'

        A template for the name of the source. Used to prevent code duplication between
        `name` and `get_value`.

        For non-ChainedSources, `name` and `get_value` use the returned string directly.

        For ChainedSources, `name` and `get_value` expect the return to be a format string
        with `{0}` present - `name` and `get_value` will apply different values to this function's
        returned format string.
