Not just nice, but necessary for consistency—if I have a variable change which 
also causes two more to change, it is absolutely critical that either all three 
change, or that the whole thing fail.  You just can’t do that without 
begin/end, AFAIK, unless you have a followup that checks all three once all are 
done—and what if you lose power or otherwise crash before that happens?
