 ## Description
 
 By default, closures capture their environment by borrowing. Or you can use `move`-closure
-to move environment. However, often you want to give copy of some data to closure.

 Use variable rebinding in separate scope for that.

+    move || {

 Closure uses same variable names as surrounding code whether data are copied or moved.

+## Disadvantages
+
+Additional indentation of closure body.
