I'll translate for you

my @in  = ( 2, 3 );
my @out = ( 1, \@in, 4 );
my $r   = \@out;
$r = [ 1, [ 2, 3 ], 4 ];
$r->[1]->@*;  # equivalent to @{ $r->[1] }
              # equivalent to @{ $out[1] }
              # equivalent to @{ \@in }

`How does that answers if $r->[1]@* is valid?` It doesn't, it answers only the question I understood `Why is the second arrow necessary in $r->[1]->@?` I've no idea if `$r->[1]@` I usually don't run development builds of perl From the documentation I would guess the answer is no, but the test suite might be more revealing https://metacpan.org/source/SHAY/perl-5.19.5/t/op/postfixderef.t ; short look, looks like answer is no	[reply] [d/l] [select]
