Is there a bug?  There a lots of places where you want to modify $_
within loops.  Consider:

                for (@names){
                        s/\b([a-z])/toupper($1)/g;
                        print;
                }
for one example.


Who says that modifying $_ here causes a problem?  It doesn't
break the looping.  Do they want it break the looping, as in
a for(;;) construction?
