+ *
+ * Example #1:

+ * The array ["foo", "bar", "blitz"] will only be included in the calldata once.

+ * function f((string, uint, bytes), string, uint, bytes)

+ *
+ * @TODO #1:
+ * This optimization strategy handles blocks that are exact duplicates of one another.
+ * But what if some block is a combination of two other blocks? Or a subset of another block?
+ * This optimization problem is not much different from the current implemetation.
+ * Instead of tracking "observed" hashes, at each node we would simply do pattern-matching on the calldata.
+ * This strategy would be applied after assigning offsets to the tree, rather than before (as in this strategy).
+ * Note that one consequence of this strategy is pointers may resolve to offsets that are not word-aligned.
+ * This shouldn't be a problem but further investigation should be done.
+ *
+ * @TODO #2:
+ * To be done as a follow-up to @TODO #1.
+ * Since we optimize from the bottom-up, we could be affecting the outcome of a later potential optimization.
+ * For example, what if by removing one duplicate value we miss out on optimizing another block higher in the tree.
+ * To handle this case, at each node we can store a candidate optimization in a priority queue (sorted by calldata size).
