Thanks @exenGT, I added a question to the associated issue. |

@janosh All your suggestions have been addressed in my latest commits. |

@exenGT Looking good! Could you add a test in test_standard_transformations.py?

| # fill the sublattice sites with pure-element atoms | ||
| self.all_structures = [] |

is it necessary to store the structures on the transformation instance? might balloon mem usage if people create many of these RandomStructureTransformations.

I used this syntax because there is an is_one_to_many property in the class; should it be False by default? (I see it is True for other classes)

I think there's no connection between is_one_to_many (that part is good) and storing the transformed structures on the transformation instance?

Could you elaborate more on this? I feel I'm not totally understanding. For example, the apply_transformation method of OrderDisorderedTransformation returns a list of structures as well (self._all_structures). What is the issue with this approach?

Could you explain the need to store all structures for later? Why not just return them and let them be garbage collected if they go out of scope in the user's code? Currently they live as long as the Transformation instance which is not great given structures are notoriously mem hungry.

I see. This feature is here simply because I'm copying what's been written for the other transformations. If you think it's not a good approach, then I can modify it in my code accordingly.
