GeneratorWrapper also runs afoul of some places where I do explicit type checking instead of duck typing (isinstance(x, types.GeneratorType)). Using the Generator ABC doesn't work because the generator methods are set as attributes on __init__ instead of defined on the class. The methods should be defined on the class, even if they're overwritten with instance attributes later for speed.  (related: inspect.iscoroutine is defined in terms of Should inspect.isgenerator be redefined to use the new
