Structured editing is an invaluable tool when working with Lisp languages (elsip, lisp, clojure, etc) as it enables you to easily move code around without breaking the structural syntax of the language.
Clojure has very precise syntax as everything is contained in a list or similar structure. It is very simple to navigate the structure of Clojure code by jumping from expression to expression.
This well defined structure also makes it trivial to move expressions around, giving you a simple way to develop and refactor your code.

Smartparents For Writing Structured Text
Spacemacs uses smartparens to help you write structured code really fast and also move expressions around. Smartparens is a newer implementation of the classic paredit package.
Lisp State For Manipulating Structured Text
Spacemacs includes lisp-state,
SPC k . for refactoring Lisp base languages like Clojure. In this lisp-state you can use the normal Vim keys to navigate your code by its structure. You can also move symbols and expressions around without risking unmatched parenthesis or other structure characters (using
