>...you would have to "notify" the array itself that it has changed..
I don't get what you mean..or maybe I do...? Do you mean that if there are two arrays with non-overlapping views of the same data then modifying one will change the mutablehash of both? That's true I guess, and I hadn't considered it, but I don't think it matters hugely because inequality of mutablehashes is not supposed to imply inequality of data. -- View this message in context: http://numpy-discussion.10968.n7.nabble.com/feature-request-increment-counter-on-write-check-tp41015p41018.html Sent from the Numpy-discussion mailing list archive at Nabble.com. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
