No, you are only grabbing the first element of @_. You should either pass
the array as a reference (best way), or just grab up the entire @_.
Keep in mind that if you pass an array and any scalars as arguments, they
will all be flattened out into @_, as a single list. This is why passing
a reference is better, to differentiate lists and scalars.
SomeFunction([qw(one two three)]);
sub SomeFunction {
my $array = shift;
foreach(@{$array}) {
print "$_\n";
}
}
