Well, I said "basically" never. Like all blanket statements, there are exceptions. Perhaps I should have said: Use my by default, use local when you understand why you can't use my in a specific situation. You can create 'stack-like' aggregates with local as you demonstrate, but you need a very good reason. 

# some good reasons:

# if you modify a side-effect global like $/, 
# do it in the smallest scope possible:
my $slurped = do { local $/; <$some_Fhand> };

# override an element of a global aggregate in a 
# limited scope:
{
   local $SIG{"ALRM"} = \&some_handler;
   alarm $timeout;
   some_action();
}

Of course, I agree that understanding the difference is much better than applying a blanket maxim. (Which is why I pointed to an article that does just that.)
