Hi,
Hello,
I came across this construct
foreach $i ( @{$y} ) {
#do something
}
Is @ referring to some default array that doesn't need to be declared?
Also it's using the associative version of an array?
I always thought only hashes were associative.
$y is a reference to an array and @{$y} (or simply @$y) is dereferencing
that array reference.
