-        //            label  - The next point at which to resume evaluation of the generator body.
-        //            trys   - A stack of protected regions (try/catch/finally blocks).
-        //            ops    - A stack of pending instructions when inside of a finally block.
-        //  f       A value indicating whether the generator is executing.

-        //  t       A temporary variable that holds one of the following values (note that these
-        //          cases do not overlap):
-        //          - The completion value when resuming from a `yield` or `yield*`.
-        //          - The error value for a catch block.
-        //          - The current protected region (array of try/catch/finally/end labels).
-        //          - The verb (`next`, `throw`, or `return` method) to delegate to the expression
-        //            of a `yield*`.

-        // The __generator helper understands a limited set of instructions:
-        //  0: next(value?)     - Start or resume the generator with the specified value.
-        //  1: throw(error)     - Resume the generator with an exception. If the generator is
-        //                        suspended inside of one or more protected regions, evaluates
-        //                        any intervening finally blocks between the current label and
-        //                        the nearest catch block or function boundary. If uncaught, the
-        //                        exception is thrown to the caller.
-        //  2: return(value?)   - Resume the generator as if with a return. If the generator is
-        //                        suspended inside of one or more protected regions, evaluates any
-        //                        intervening finally blocks.
-        //  3: break(label)     - Jump to the specified label. If the label is outside of the
-        //                        current protected region, evaluates any intervening finally
-        //                        blocks.
-        //  4: yield(value?)    - Yield execution to the caller with an optional value. When
-        //                        resumed, the generator will continue at the next label.
-        //  5: yield*(value)    - Delegates evaluation to the supplied iterator. When
-        //                        delegation completes, the generator will continue at the next
-        //                        label.
-        //  6: catch(error)     - Handles an exception thrown from within the generator body. If
-        //                        the current label is inside of one or more protected regions,
-        //                        evaluates any intervening finally blocks between the current
-        //                        label and the nearest catch block or function boundary. If
-        //                        uncaught, the exception is thrown to the caller.
-        //  7: endfinally       - Ends a finally block, resuming the last instruction prior to
-        //                        entering a finally block.

+    //            ops    - A stack of pending instructions when inside of a finally block.
+    //  f       A value indicating whether the generator is executing.

+    //  t       A temporary variable that holds one of the following values (note that these

+    //          - The completion value when resuming from a `yield` or `yield*`.
+    //          - The error value for a catch block.
+    //          - The current protected region (array of try/catch/finally/end labels).

+    //                        suspended inside of one or more protected regions, evaluates
+    //                        any intervening finally blocks between the current label and

+    //                        exception is thrown to the caller.
+    //  2: return(value?)   - Resume the generator as if with a return. If the generator is
+    //                        suspended inside of one or more protected regions, evaluates any
+    //                        intervening finally blocks.
+    //  3: break(label)     - Jump to the specified label. If the label is outside of the
+    //                        current protected region, evaluates any intervening finally
+    //                        blocks.
+    //  4: yield(value?)    - Yield execution to the caller with an optional value. When
+    //                        resumed, the generator will continue at the next label.
+    //  5: yield*(value)    - Delegates evaluation to the supplied iterator. When
+    //                        delegation completes, the generator will continue at the next
+    //                        label.
+    //  6: catch(error)     - Handles an exception thrown from within the generator body. If

+    //                        evaluates any intervening finally blocks between the current
