A common way to access an array or a hash is one scalar element at a time. You can also subscript a list to get a single element from it.

And by doing so, you get a list slice. A single-index slice is still a slice. The difference between a slice and indexing is the context in which the index expression is evaluated. 

my @indexes = (3);

my @array = (0,1,2,3,4);
print($array[@indexes], "\n");  # 1 => index
print(@array[@indexes], "\n");  # 3 => slice

print((0,1,2,3,4,5)[@indexes], "\n");  # 3 => slice

There's no native syntax to index a list.
