 - You can show how the value of the block changes by changing the last line in
   the block. For instance, adding/removing a semicolon or using a `return`.
-- Show that a variable's scope is limited by adding a `b` in the inner block in
-  the last example, and then trying to access it outside that block.
-- Shadowing is different from mutation, because after shadowing both variable's
-  memory locations exist at the same time. Both are available under the same
-  name, depending where you use it in the code.
-- A shadowing variable can have a different type.
-- Shadowing looks obscure at first, but is convenient for holding on to values
-  after `.unwrap()`.
