- Inconsistent id() vs direct access use in generated code
+
+? Move change_callback out of image
+
+ We incur a bit of overhead in case of a batch (e.g., ~80KB for
+ a batch size of 5000 on 64-bit) since we don't use this callback
+ in all but the first element.
+
+ The idea is to move it to the object statements, however, there
+ are several places that need to access it that only got the image
+ (e.g., init(image)). Storing a pointer in the image doesn't make
+ sense since the struct itself is two pointers.
+
+ So it is not clear this is worth the effort. See also a separate
+ paper with some more thoughts on this.
