Hi Mark,</div>
<div class="elementToProof" style="font-family: "Calibri Light", "Helvetica Light", sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
Very good question - and the answer is unfortunately, no. Transforms are allowed to reuse code models, and I think the bound Code attribute expansion also returns duplicate load or store instructions.</div>
<div class="elementToProof" style="font-family: "Calibri Light", "Helvetica Light", sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
To ensure identity, I think tracking a pair of (index, element) is better.</div>
