in reply to $_ and list flattening with map()

I always thought map just returns copies of the values?

my @a = qw(1 2); my @b = \(@a); my @c = \(map $_,@a); print "Addresses do not match$/" unless "@b" eq "@c"; __END__ Addresses do not match

Of course, changing your map to:

${$_}++ for map \(@$_),@{$a};

Will make it work as expected.
