in reply to Re^2: my $x or my ($x)
in thread my $x or my ($x)

The only warning I can give is that using an undef in the list will throw warnings (errors?) in older versions of perl:
my (undef, $foo, undef, $bar) = @array;


Never fear. Just move your my.

(undef, my $foo, undef, my $bar) = @array;

This is particularly more useful in cases where you already have a declared variable.
my $foo = "ab"; (my $avar, $foo) = ($foo =~ /(.)(.)/);


my @a=qw(random brilliant braindead); print $a[rand(@a)];

    I prefer slicing. Instead of:

    my (undef, $foo, undef, $bar) = @array;

    or

    (undef, my $foo, undef, my $bar) = @array;

    do:

    my ($foo, $bar) = @array[1,3];

    e.g.

    my ($size, $mtime) = (stat $filename)[7,9];
