AIUI the OP is looking to implement __dir__, but make use of *what
dir() would have returned* in that function. Something like:
class Magic:
def __getattr__(self, attr):
if attr in self.generatables:
return self.generated_value(attr)
raise AttributeError
def __dir__(self):
return default_dir(self) + self.generatables
For that purpose, is it possible to use super().__dir__()? Are there
any considerations where that would fail?
