D'après le cookbook de o'reilly "reverse" et une "boucle inversée" devrait
donner la même chose :

# reverse @ARRAY into @REVERSED
@REVERSED = reverse @ARRAY;Or use a for loop:

for ($i = $#ARRAY; $i >= 0; $i--) {
# do something with $ARRAY[$i]
}

La fonction reverse ne fait pas de modification en place.
Si c'est ce que l'on veut, il ne faut pas faire

reverse @myArray;

may

@myArray = reverse @myArray;
