So, in the first case, I can still compare the __array_interfaces__, right ?
If they're equal, then the two arrays are strictly equivalent. In the second
case, even if the arrays share some overlapping data, they're intrinsically
different, so a test on whether the data has been copied/moved around would
Well, thank y'all again.
