Right, it is actually a "range" - an object that generates the 
result on-demand, so it doesn't do work you don't actually need. 
If you don't need an array per se, you can just foreach over it 
and print them or further work on it without the cost of creating 
a new array.

But, if you need to copy it into a new array, use `.array` at the 
end.
