This cheat sheet is accurate. What imo you don't get from it
is the solid structure that paredit provides. You cannot unbalance
your parens without some effort (like explicitly cutting out a
region). This frees up the mental effort of checking out if you got
things correct. Its a major plus to program in lisp like languages,
because you can leverage the tree structure of the code more easily.
That's my view of it.
