;;; Commentary:
;; Evil bindings for `lispy-mode'.
;; This is not included in the default init list for `evil-collection'.
;; Add `lispy' to `evil-collection-mode-list' to use this package.
;; e.g. (push 'lispy evil-collection-mode-list)
;; This file is meant to be an experimental ground for `lispy' keybindings
;; and the changes here are intended to be created as a PR to the main `lispy'
;; repository.
;; PRs, tweaks or comments are very welcome!
