 The main reasons you might want to consider `nvim-paredit` instead are:
 
-+ Easier configuration and an exposed lua API
-+ Control over how the cursor is moved during slurp/barf. (For example if you don't want the cursor to always be moved)
-+ Recursive slurp/barf operations. If your cursor is in a nested form you can still slurp from the forms parent(s)
-+ Subjectively better out-of-the-box keybindings
