Probably a stupid question, but why do you want to use el_same? As I understand it, el_same creates a copy. Why not use the original, if we know that it will not change anything.
As I understand, one "elem" can appear only once in the backend tree. When I tried otherwise, I got asserts in the optimizer, and I've never seen code that reuses elem nodes.
