+Unlike the example of ShiftReset, interpreting SubJump first or interpreting it later results in the same behavior.
+This is because the `getCC` version of SubJump differs from that of ShiftReset in that it returns a "pseudo current continuation."
+While `ShiftReset.getCC` returns the real current continuation,
+`SubJump.getCC` returns an action that contains only the operation `SubJump.jump` which jumps to the control flow at that point in time.
+That is, `SubJump.getCC` can be represented in the following pseudo-code:
+
+@
+SubJump.getCC = pure $ SubJump.jump (goto label reference to the code line at the point where this SubJump.getCC is called)
+@
+
+First, `runLocal` modifies all `ask` within the local scope.
+In the case of ShiftReset, since `getCC` returns the real current continuation, the modification is also applied to `ask` within the continuation.
+However, in this case, the `k` returned by `getCC` only contains `SubJump.jump`, so it is not subject to modification.

+        & (evalState 0 . unkey @"counter")
+        & runEff
+
+{- |
+...In contrast to the above behavior, if you want to change it, you can achieve this by converting the `Local`/`Ask` effects into `State` effects and changing the semantics.
+In this case, the semantics of `local` are transformed not to modify `ask` within the scope, but instead to save the current environment state value,
+overwrite the state, and restore the saved value after the scope ends (`localToState`).
