I've addressed the last comments.
Regarding the deterministic hashing and ordering of the graph: changing
anything but the user function changes the hash (if not specified manually).
If we don't want this, we will run into collisions when you have the same
transformations more than once in the graph. I think it is OK to be aggressive
with this in the beginning. I've tried to make this point clearer in the docs.
