WATCH key                                      Watch should still work
[regular ops]                                  ...
MULTI                                          Multi call to create more interesting operations
SADD foo bar                                   Basic mutation. No interesting result.
SMEMBERS foo                                   Pulls members of the set... usually returned to client but not here
SORT @2 DESC LIMIT 10 GET qux_* GET #          Does a sort on the 2nd multi command's result
COPY @3 stuff                                  Copy one key to another. One way to save multi results directly
EXEC @3                                        Executes but only returns 3rd bulk result
