One of the benefits of the lisp style syntax of clojure is its very easy to navigate its structure, eg. parenthesis. You can easily jump between expressions as they are defined unambiguously.
This well defined structure makes it trivial to move expressions around, giving you a simple way to refactor the internals of your code.
Writing Structured Text
Spacemacs uses smart parens to help you write structured code really fast and also move expressions around. Smart parens is a newer implementation of the classic paredit package.
TODO Check out https://github.com/expez/evil-smartparens as it seems to provide the desired smartparens behaviour for Vim normal mode that I get in Emacs mode.
Manipulating Structured Text
Spacemacs includes an Evil lisp-state,
SPC k . for refactoring Lisp base languages like Clojure. In this lisp-state you can use single character commands to move symbols and expressions around without risking unmatched parenthesis or other structure characters.
