@{ ... } is a dereferencing operation. It's useful to note that the { ... } is just a normal code block and can contain any code you want, as long as it returns an array reference.

For instance, you could call a subroutine which returns an array reference:

 foreach my $case ( $justice_wheels->spin() ) {
     my $verdict = Conviction::Felony->new( $case->defendant() );
     push @{ $case->defendant()->get_felony_convictions() }, $verdict;
     push @{ $case->judge()->get_felony_convictions() }, $verdict;
 }

Yep, definitely feeling silly today...
