Perl reference dereference 
www.perlmania.or.kr에서 본인이 답변한 내용정리


차례대로 정리를 해보면 perl에서 reference를 dereference 할때는 [sigil]{}연산자를
사용합니다. 여기서 sigil은 결과로 어떤 데이터 타입을 가질것인가를 결정하는거죠.

@array = ( "one", "two", "three", "four", [10, 20, 30, 40, 50] );
$arrayref = \@array;
인 상태에서 $arrayref 안의 one을 가져오려면 해당값은 scalar이므로 sigil은 $가 되고
