+# Range Into List Using Comprehensions
+
+Using an _identity_ comprehension and the `:into` option, we can easily
+convert a range into a list.
+
+```elixir
+> for x <- 1..10, into: [], do: x
+[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
+```
+
+Check out [the docs for the `:into`
+option](http://elixir-lang.org/getting-started/comprehensions.html#the-into-option)
+for more details.
