+    attempts to cast them to the function signature of the attached function

+    verification that the inputs to this operation have any relation to the
+    outputs outside of basic dominance requirements needed for the replacement.

+    The casting materialization functions are specified in the graph region of

+    ops within the region is irrelevant.
