+    Using this operation, the dialect can model the data-sharing attributes of
+    `private` and `firstprivate` variables on the IR level. This means that of
+    "eagerly" privatizing variables in the frontend, we can instead model which
+    variables should be privatized and only materialze the privatization when
+    necessary; e.g. directly before lowring to LLVM IR.
