     Refactor OpSet class. Moved OpSet to separate header file and add
-    ``contains`` and ``diference`` methods based on ``std::set::contains``
+    ``contains`` and ``difference`` methods based on ``std::set::contains``
     and ``std::algorithm::set_difference``. These replace the removed invalid
     and validate instructions from OpSet, but with the order reversed. It
     returns a list of other ops not in current opset rather than opset
